V. The Other Types of Indulgenced Grants
1. A few more types of indulgenced grants are here added to the three general types listed above in I-III. These other types exhibit a distinctive character of their own since they take into consideration the traditions of the past as well as the concerns of our own times.
All these other types of grant complement one another. in offering the gift of an indulgence they intend to lead the Christian faithful to perform works of devotion, charity, and penitence and to lead them by means of charity to closer union with the body of the Church and with Christ, its head. 
2. Certain prayers are listed in this section. These prayers merit great respect owing to their divine inspiration or their antiquity and upon their more
or less universal usage, e.g., the Creed (no. 16); the De Profundis (no. 19); the Magnificat (no. 30); the Ancient Prayer to Mary (no. 57); the Hail, Holy Queen (no. 51); the Prayer for All Occasions (no. 1); and the Prayer of Thanksgiving (no. 7).
Upon close inspection it becomes obvious that these prayers are already included in the first general type of grant. For these prayers are recited in the course of their everyday lives by the Christian faithful with hearts raised
in humble trust to God.
As examples of such overlapping with the first general type we can mention the Prayer for All Occasions and the Prayer of Thanksgiving, since they are recited during the course of "carrying out one's duties."
But it seemed helpful to list these prayers separately as being endowed with indulgences in order to eliminate any doubt and to indicate their prominence.
3. In this section are also found individual works to which an indulgence is attached. The grant of a partial indulgence is sometimes expressly stated and explained; but often it is indicated only by the rubric: partial indulgence.
When some work is endowed with a plenary indulgence owing to special circumstances, the plenary grant and the special circumstances which define the work in detail are expressly noted for each and every such grant. For the sake
of brevity, the other types of works endowed with indulgences are not so noted; and it is to be understood that the indulgence attached to these works is a partial one.
As stated in norm 23, the requirements for obtaining a plenary indulgence are: the execution of the work, the fulfillment of the three conditions, and that full disposition of spirit which excludes all attachment to sin.
4. When the work to which a plenary indulgence is attached can easily be divided into parts (e.g., the division of the Marian Rosary into decades), a
person who owing to some reasonable cause cannot complete the entire work can obtain a partial indulgence for that part which was completed.
5. Worth special mention are those grants which list works by which the Christian faithful, by performing any one of them, can obtain a plenary indulgence every day of the year:
- adoration of the Blessed Sacrament for at least one half hour (no. 3);
- devout reading of the Sacred Scriptures for at least one half hour (no. 50);
- the devout performance of the Stations of the Cross (no. 63);
- the recitation of the Marian Rosary in a church or oratory, with members of the family, in a religious Community, or in a pious association (no. 48).
But even in these instances what is stated in norm 21, paragraph 1, retains its force, namely, a plenary indulgence can be obtained but once a day.
