II. Holy Week
27. During Holy Week, the Church celebrates the mysteries of salvation accomplished by Christ in the last days
of his life on earth, beginning with his messianic entrance into Jerusalem.
The lenten season lasts until the Thursday of this week. The Easter Triduum begins with the evening Mass of
the Lord's Supper, is continued through Good Friday with the celebration of the passion of the Lord and Holy
Saturday, to reach its summit in the Easter Vigil, and concludes with Vespers of Easter Sunday.
"The days of Holy Week, from Monday to Thursday inclusive, have precedence over all other celebrations." 
It is not fitting that baptisms and confirmation be celebrated on these days.
A. Passion Sunday (Palm Sunday)
28. Holy Week begins on Passion (or Palm) Sunday, which joins the foretelling of Christ's regal triumph and the
proclamation of the passion. The connection between both aspects of the paschal mystery should be shown
and explained in the celebration and catechesis of this day. 
29. The commemoration of the entrance of the Lord into Jerusalem has, according to ancient custom, been
celebrated with a solemn procession, in which the faithful in song and gesture imitate the Hebrew children
who went to meet the Lord, singing "Hosanna." 
The procession may take place only once, before the Mass that has the largest attendance, even if this
should be in the evening of either Saturday or Sunday. The congregation should assemble in a secondary church
or chapel or in some other suitable place distinct from the church to which the procession will move.
In this procession, the faithful carry palm or other branches. The priest and the ministers, also carrying
branches, precede the people. 
The palms or branches are blessed so that they can be carried in the procession. The palms should be taken home,
where they will serve as a reminder of the victory of Christ, which they celebrated in the procession.
Pastors should make every effort to ensure that this procession in honor of Christ the King be so prepared
and celebrated that it is of great spiritual significance in the life of the faithful.
The Missal, in order to commemorate the entrance of the Lord into Jerusalem, in addition to the solemn
procession described above, gives two other forms, not simply for convenience, but to provide for those situations
when it will not be possible to have the procession.
The second form is that of a solemn entrance, when the procession cannot take place outside of the church.
The third form is a simple entrance such as is used at all Masses on this Sunday that do not have the solemn entrance. 
31. Where the Mass cannot be celebrated, there should be a celebration of the word of God on the theme of the
Lord's messianic entrance and passion, either on Saturday evening or on Sunday at a convenient time. 
32. During the procession, the choir and people should sing the chants proposed in the Roman Missal,
especially Psalms 23 and 46, as well as other appropriate songs in honor of Christ the King.
33. The passion narrative occupies a special place. It should be sung or read in the traditional way, that is,
by three persons who take the part of Christ, the narrator, and the people. The passion is proclaimed by deacons
or priests, or by lay readers. In the latter case, the part of the Christ should be reserved to the priest.
The proclamation of the passion should be without candles and incense; the greeting and the sings of the cross
are omitted; and only a deacon asks for the blessing, as he does before the Gospel. 
For the spiritual good of the faithful, the passion should be proclaimed in its entirety, and the readings
that proceed it should not be omitted.
34. After the passion has been proclaimed, a homily is to be given.
B. The Chrism Mass
35. The Chrism Mass, which the bishop concelebrates with his presbyterium, and at which the Holy Chrism is
consecrated and the oils blessed, manifests the communion of the priests with their bishop in the same
priesthood and ministry of Christ.  The priests who concelebrate with the
bishop should come to this Mass from different parts of the diocese, thus showing in the consecration of the Chrism
to be his witnesses and cooperators, just as in their daily ministry, they are his helpers and counselors.
The faithful are also to be encouraged to participate in this Mass and to receive the sacrament of the Eucharist.
Traditionally, the Chrism Mass is celebrated on the Thursday of Holy Week. If, however, it should prove to be difficult
for the clergy and people to gather with the bishop, this rite can be transferred to another day, but one always close to
Easter.  The Chrism and the oil of catechumens is to be used in the celebration of the
sacraments of initiation on Easter night.
36. There should be only one celebration of the Chrism Mass, given its significance in the life of the diocese, and it
should take place in the cathedral or, for pastoral reasons, in another church 
that has a special significance.
The Holy oils can be brought to the individual parishes before the celebration of the evening Mass of the Lord's Supper,
or at some other suitable time. This can be a means of catechizing the faithful about the use and effects of the
Holy oils and Chrism in Christian life.
C. The Penitential Celebrations in Lent
37. It is fitting that the lenten season should be concluded, both for the individual Christian as well
as for the whole Christian community, with a penitential celebration, so that they may be helped to prepare to celebrate
more fully the paschal mystery. 
These celebrations, however, should take place before the Easter Triduum and should not immediately precede the
evening Mass of the Lord's Supper.
