Chapter IV: The General Arrangement of Readings for Mass
1. The Pastoral Purpose of the Order of Readings for Mass
58. On the basis of the intention of the Second Vatican Council, the Order of
Readings provided by the Lectionary of the Roman Missal has been composed above
all for a pastoral purpose. To achieve this aim, not only the principles
underlying this new Order of Readings but also the lists of texts that it
provides have been discussed and revised over and over again, with the
cooperation of a great many experts in exegetical, liturgical, catechetical, and
pastoral studies from all parts of the world. The Order of Readings is the fruit
of this combined effort.
The prolonged use of this Order of Readings to proclaim and explain Sacred
Scripture in the Eucharistic celebration will, it is hoped, prove to be an
effective step toward achieving the objective stated repeatedly by the Second
Vatican Council. 
59. The decision on revising the Lectionary for Mass was to draw up and edit
a single, rich, and full Order of Readings that would be in complete accord with
the intent and prescriptions of the Second Vatican Council.
 At the same time, however, the Order was
meant to be of a kind that would meet the requirements and usages of particular
Churches and celebrating congregations. For this reason, those responsible for
the revision took pains to safeguard the liturgical tradition of the Roman Rite,
but valued highly the merits of all the systems of selecting, arranging, and
using the biblical readings in other liturgical families and in certain
particular Churches. The revisers made use of those elements that experience has
confirmed, but with an effort to avoid certain shortcomings found in the
preceding form of the tradition.
60. The present Order of Readings for Mass, then, is an arrangement of
biblical readings that provides the faithful with a knowledge of the whole of
God's word, in a pattern suited to the purpose. Throughout the liturgical year,
but above all during the seasons of Easter, Lent, and Advent, the choice and
sequence of readings are aimed at giving Christ's faithful an ever-deepening
perception of the faith they profess and of the history of salvation.
 Accordingly, the Order of Readings
corresponds to the requirements and interests of the Christian people.
61. The celebration of the Liturgy is not in itself simply a form of
catechesis, but it does contain an element of teaching. The Lectionary of the
Roman Missal brings this out  and therefore
deserves to be regarded as a pedagogical resource aiding catechesis.
This is so because the Order of Readings for Mass aptly presents from Sacred
Scripture the principal deeds and words belonging to the history of salvation.
As its many phases and events are recalled in the liturgy of the word, it will
become clear to the faithful that the history of salvation is continued here and
now in the representation of Christ's paschal mystery celebrated through the
62. The pastoral advantage of having in the Roman Rite a single Order of
Readings for the Lectionary is obvious on other grounds. All the faithful,
particularly those who for various reasons do not always take part in Mass with
the same assembly, will everywhere be able to hear the same readings on any
given day or in any liturgical season and to meditate on the application of
these readings to their own concrete circumstances. This is the case even in
places that have no priest and where a deacon or someone else deputed by the
bishop conducts a celebration of the word of God.
63. Pastors may wish to respond specifically from the word of God to the
concerns of their own congregations. Although they must be mindful that they are
above all to be heralds of the entire mystery of Christ and of the Gospel, they
may rightfully use the options provided in the Order of Readings for Mass. This
applies particularly to the celebration of a ritual or votive Mass, a Mass in
honor of the Saints, or one of the Masses for various needs and occasions. With
due regard for the general norms, special faculties are granted concerning the
readings in Masses celebrated for particular groups.
2. The Principles of Composition of the Order of Readings for Mass
64. To achieve the purpose of the Order of Readings for Mass, the parts have
been selected and arranged in such a way as to take into account the sequence of
the liturgical seasons and the hermeneutical principles whose understanding and
definition has been facilitated by modern biblical research.
It was judged helpful to state here the principles guiding the composition of
the Order of Readings for Mass.
a) THE CHOICE OF TEXTS
65. The course of readings in the Proper of Seasons is arranged as follows.
Sundays and festive days present the more important biblical passages. In this
way the more significant parts of God's revealed word can be read to the
assembled faithful within an appropriate period of time. Weekdays present a
second series of texts from Sacred Scripture and in a sense these complement the
message of salvation explained on festive days. But neither series in these main
parts of the Order of Readings - the series for Sundays and festive days and that
for weekdays - is dependent on the other. The Order of Readings for Sundays and
festive days extends over three years; for weekdays, over two. Thus each runs
its course independently of the other.
The sequence of readings in other parts of the Order of Readings is governed
by its own rules. This applies to the series of readings for celebrations of the
Saints, ritual Masses, Masses for various needs and occasions, votive Masses, or
Masses for the dead.
b) THE ARRANGEMENT OF THE READINGS FOR SUNDAYS AND FESTIVE DAYS
66. The following are features proper to the readings for Sundays and festive
1. Each Mass has three readings: the first from the Old Testament,
the second from an Apostle (that is, either from a Letter or from the Book of
Revelation, depending on the season), and the third from the Gospels. This
arrangement brings out the unity of the Old and New Testaments and of the
history of salvation, in which Christ is the central figure, commemorated in his
2. A more varied and richer reading of Sacred Scripture on Sundays and festive
days results from the three-year cycle provided for these days, in that the same
texts are read only every fourth year. 
3. The principles governing the Order of Readings for Sundays and festive days
are called the principles of "harmony" and of "semicontinuous
reading." One or the other applies according to the different seasons of
the year and the distinctive character of the particular liturgical season.
67. The best instance of harmony between the Old and New Testament readings
occurs when it is one that Scripture itself suggests. This is the case when the
doctrine and events recounted in texts of the New Testament bear a more or less
explicit relationship to the doctrine and events of the Old Testament. The
present Order of Readings selects Old Testament texts mainly because of their
correlation with New Testament texts read in the same Mass, and particularly
with the Gospel text.
Harmony of another kind exists between texts of the readings for each Mass
during Advent, Lent, and Easter, the seasons that have a distinctive importance
In contrast, the Sundays in Ordinary Time do not have a distinctive
character. Thus the text of both the apostolic and Gospel readings are arranged
in order of semicontinuous reading, whereas the Old Testament reading is
harmonized with the Gospel.
68. The decision was made not to extend to Sundays the arrangement suited to
the liturgical seasons mentioned, that is, not to have an organic harmony of
themes devised with a view to facilitating homiletic instruction. Such an
arrangement would be in conflict with the genuine conception of liturgical
celebration, which is always the celebration of the mystery of Christ and which
by its own tradition makes use of the word of God not only at the prompting of
logical or extrinsic concerns but spurred by the desire to proclaim the Gospel
and to lead those who believe to the fullness of truth.
c) THE ARRANGEMENT OF THE READINGS FOR WEEKDAYS
69. The weekday readings have been arranged in the following way.
1. Each Mass has two readings: the first is from the Old Testament
or from an Apostle (that is, either from a Letter or from the Book of
Revelation), and during the Easter season from the Acts of the Apostles; the
second, from the Gospels.
2. The yearly cycle for Lent has its own principles of arrangement, which take
into account the baptismal and penitential character of this season.
3. The cycle for the weekdays of Advent, the Christmas season, and the Easter
season is also yearly and the readings thus remain the same each year.
4. For the thirty-four weeks of Ordinary Time, the weekday Gospel readings are
arranged in a single cycle, repeated each year. But the first reading is
arranged in a two-year cycle and is thus read every other year. Year I is used
during odd-numbered years; Year II, during even-numbered years.
Like the Order for Sundays and festive days, then, the weekday Order of
Readings is governed by similar application of the principles of harmony and of
semicontinuous reading, especially in the case of seasons with their own
d) THE READINGS FOR CELEBRATIONS OF THE SAINTS
70. Two series of readings are provided for celebrations of the Saints.
1. The Proper of Saints provides the first series, for solemnities,
feasts, or memorials and particularly when there are proper texts for one or
other such celebration. Sometimes in the Proper, however, there is a reference
to the most appropriate among the texts in the Commons as the one to be given
2. The Commons of Saints provide the second, more extensive group of readings.
There are, first, appropriate texts for the different classes of Saints
(martyrs, pastors, virgins, etc.), then numerous texts that deal with holiness
in general. These may be freely chosen whenever the Commons are indicated as the
source for the choice of readings.
71. As to their sequence, all the texts in this part of the Order of Readings
appear in the order in which they are to be read at Mass. Thus the Old Testament
texts are first, then the texts from the Apostles, followed by the psalms and
verses between the readings, and finally the texts from the Gospels. The
rationale of this arrangement is that, unless otherwise noted, the celebrant may
choose at will from such texts, in view of the pastoral needs of the
congregation taking part in the celebration.
e) READINGS FOR RITUAL MASSES, MASSES FOR VARIOUS NEEDS AND OCCASIONS, VOTIVE
MASSES, AND MASSES FOR THE DEAD
72. For ritual Masses, Masses for various needs and occasions, votive Masses,
and Masses for the dead, the texts for the readings are arranged as just
described, that is, numerous texts are grouped together in the order of their
use, as in the Commons of Saints.
f) THE MAIN CRITERIA APPLIED IN CHOOSING AND ARRANGING THE READINGS
73. In addition to the guiding principles already given for the arrangement
of readings in the individual parts of the Order of Readings, others of a more
general nature follow.
1) The Reservation of Some Books to Particular Liturgical Seasons
74. In this Order of Readings, some biblical books are set aside for
particular liturgical seasons on the basis both of the intrinsic importance of
subject matter and of liturgical tradition. For example, the Western (Ambrosian
and Hispanic) and Eastern tradition of reading the Acts of the Apostles during
the Easter season is maintained. This usage results in a clear presentation of
how the Church's entire life derives its beginning from the paschal mystery. The
tradition of both West and East is also retained, namely the reading of the
Gospel of John in the latter weeks of Lent and in the Easter season.
Tradition assigns the reading of Isaiah, especially the first part, to
Advent. Some texts of this book, however, are read during the Christmas season,
to which the First Letter of John is also assigned.
2) The Length of the Texts
75. A middle way is followed in regard to the length of texts. A distinction
has been made between narratives, which require reading a fairly long passage
but which usually hold the attention of the faithful, and texts that should not
be lengthy because of the profundity of their doctrine.
In the case of certain rather lengthy texts, longer and shorter versions are
provided to suit different situations. The editing of the shorter version has
been carried out with great caution.
3) Difficult Texts
76. In readings for Sundays and solemnities, texts that present real
difficulties are avoided for pastoral reasons. The difficulties may be
objective, in that the texts themselves raise profound literary, critical, or
exegetical problems; or the difficulties may lie, at least to a certain extent,
in the ability of the faithful to understand the texts. But there could be no
justification for concealing from the faithful the spiritual riches of certain
texts on the grounds of difficulty if the problem arises from the inadequacy
either of the religious education that every Christian should have or of the
biblical formation that every pastor of souls should have. Often a difficult
reading is clarified by its correlation with another in the same Mass.
4) The Omission of Certain Verses
77. The omission of verses in readings from Scripture has at times been the
tradition of many liturgies, including the Roman liturgy. Admittedly such
omissions may not be made lightly, for fear of distorting the meaning of the
text or the intent and style of Scripture. Yet on pastoral grounds it was
decided to continue the traditional practice in the present Order of Readings,
but at the same time to ensure that the essential meaning of the text remained
intact. One reason for the decision is that otherwise some texts would have been
unduly long. It would also have been necessary to omit completely certain
readings of high spiritual value for the faithful because those readings include
some verse that is pastorally less useful or that involves truly difficult
3. Principles to Be Followed in the Use of the Order of Readings
a) THE FREEDOM OF CHOICE REGARDING SOME TEXTS
78. The Order of Readings sometimes leaves it to the celebrant to choose
between alternative texts or to choose one from the several listed together for
the same reading. The option seldom exists on Sundays, solemnities, or feasts,
in order not to obscure the character proper to the particular liturgical season
or needlessly interrupt the semicontinuous reading of some biblical book. On the
other hand, the option is given readily in celebrations of the Saints, in ritual
Masses, Masses for various needs and occasions, votive Masses, and Masses for
These options, together with those indicated in the General Instruction of
the Roman Missal and the Ordo cantus Missae,
 have a pastoral purpose. In arranging the
liturgy of the word, then, the priest should "consider the general
spiritual good of the congregation rather than his personal outlook. He should
be mindful that the choice of texts is to be made in harmony with the ministers
and others who have a role in the celebration and should listen to the opinions
of the faithful in what concerns them more directly."
1) The Two Readings before the Gospel
79. In Masses to which three readings are assigned, all three are to be used.
If, however, for pastoral reasons the Conference of Bishops has given permission
for two readings only to be used,  the
choice between the two first readings is to be made in such a way as to
safeguard the Church's intent to instruct the faithful more completely in the
mystery of salvation. Thus, unless the contrary is indicated in the text of the
Lectionary, the reading to be chosen as the first reading is the one that is
more closely in harmony with the Gospel, or, in accord with the intent just
mentioned, the one that is more helpful toward a coherent catechesis over an
extended period, or that preserves the semicontinuous reading of some biblical
2) The Longer and Shorter Forms of Texts
80. A pastoral criterion must also guide the choice between the longer and
shorter forms of the same text. The main consideration must be the capacity of
the hearers to listen profitably either to the longer or to the shorter reading;
or to listen to a more complete text that will be explained through the homily.
3) When Two Texts Are Provided
81. When a choice is allowed between alternative texts, whether they are
fixed or optional, the first consideration must be the best interest of those
taking part. It may be a matter of using the easier texts or the one more
relevant to the assembled congregation or, as pastoral advantage may suggest, of
repeating or replacing a text that is assigned as proper to one celebration and
optional to another.
The issue may arise when it is feared that some text will create difficulties
for a particular congregation or when the same text would have to be repeated
within a few days, as on a Sunday and on a day during the week following.
4) The Weekday Readings
82. The arrangement of weekday readings provides texts for every day of the
week throughout the year. In most cases, therefore, these readings are to be
used on their assigned days, unless a solemnity, a feast, or else a memorial
with proper readings occurs. 
In using the Order of Readings for weekdays attention must be paid to whether
one reading or another from the same biblical book will have to be omitted
because of some celebration occurring during the week. With the arrangement of
readings for the entire week in mind, the priest in that case arranges to omit
the less significant passages or combines them in the most appropriate manner
with other readings, if they contribute to an integral view of a particular
5) The Celebrations of the Saints
83. When they exist, proper readings are given for celebrations of the
Saints, that is, biblical passages about the Saint or the mystery that the Mass
is celebrating. Even in the case of a memorial these readings must take the
place of the weekday readings for the same day. This Order of Readings makes
explicit note of every case of proper readings on a memorial.
In some cases there are accommodated readings, those, namely, that bring out
some particular aspect of a Saint's spiritual life or work. Use of such readings
does not seem binding, except for compelling pastoral reasons. For the most part
references are given to readings in the Commons in order to facilitate choice.
But these are merely suggestions: in place of an accommodated reading or the
particular reading proposed from a Common, any other reading from the Commons
referred to may be selected.
The first concern of a priest celebrating with a congregation is the
spiritual benefit of the faithful and he will be careful not to impose his
personal preference on them. Above all he will make sure not to omit too often
or without sufficient cause the readings assigned for each day in the weekday
Lectionary: the Church's desire is that a more lavish table of the word of God
be spread before the faithful. 
There are also common readings, that is, those placed in the Commons either
for some determined class of Saints (martyrs, virgins, pastors) or for the
Saints in general. Because in these cases several texts are listed for the same
reading, it will be up to the priest to choose the one best suited to those
In all celebrations of Saints the readings may be taken not only from the
Commons to which the references are given in each case, but also from the Common
of Men and Women Saints, whenever there is special reason for doing so.
84. For celebrations of the Saints the following should be observed:
1. On solemnities and feasts the readings must be those that are
given in the Proper or in the Commons. For solemnities and feasts of the General
Roman Calendar proper readings are always assigned.
2. On solemnities inscribed in particular calendars, three readings are to be
assigned, unless the Conference of Bishops has decreed that there are to be only
two readings.  The first reading is from
the Old Testament (but during the Easter season, from the Acts of the Apostles
or the Book of Revelation); the second, from an Apostle; the third, from the
3. On feasts and memorials, which have only two readings, the first reading can
be chosen from either the Old Testament or from an Apostle; the second is from
the Gospels. Following the Church's traditional practice, however, the first
reading during the Easter season is to be taken from an Apostle, the second, as
far as possible, from the Gospel of John.
6) Other Parts of the Order of Readings
85. In the Order of Readings for ritual Masses the references given are to
the texts already published for the individual rites. This obviously does not
include the texts belonging to celebrations that must not be integrated with
86. The Order of Readings for Masses for various needs and occasions, votive
Masses, and Masses for the dead provides many texts that can be of assistance in
adapting such celebrations to the situation, circumstances, and concerns of the
particular groups taking part. 
87. In ritual Masses, Masses for various needs and occasions, votive Masses,
and Masses for the dead, since many texts are given for the same reading, the
choice of readings follows the criteria already indicated for the choice of
readings from the Common of Saints.
88. On a day when some ritual Mass is not permitted and when the norms in the
individual rite allow the choice of one reading from those provided for ritual
Masses, the general spiritual welfare of the participants must be considered.
b) THE RESPONSORIAL PSALM AND THE ACCLAMATION BEFORE THE GOSPEL READING
89. Among the chants between the readings, the psalm which follows the first
reading is of great importance. As a rule the psalm to be used is the one
assigned to the reading. But in the case of readings for the Common of Saints,
ritual Masses, Masses for various needs and occasions, votive Masses, and Masses
for the dead the choice is left up to the priest celebrating. He will base his
choice on the principle of the pastoral benefit of those present.
But to make it easier for the people to join in the response to the psalm,
the Order of Readings lists certain other texts of psalms and responses that
have been chosen according to the various seasons or classes of Saints. Whenever
the psalm is sung, these texts may replace the text corresponding to the
90. The chant between the second reading and the Gospel is either specified
in each Mass and correlated with the Gospel or else it is left as a choice to be
made from those in the series given for a liturgical season or one of the
91. During Lent one of the acclamations from those given in the Order of
Readings may be used, depending on the occasion.
 This acclamation precedes and follows the
verse before the Gospel.
