17 In seminaries and houses of religious, clerics shall be given a liturgical formation in their spiritual life. For this they will need proper direction, so that they may be able to understand the sacred rites and take part in them wholeheartedly; and they will also need personally to celebrate the sacred mysteries, as well as popular devotions which are imbued with the spirit of the liturgy. In addition they must learn how to observe the liturgical laws, so that life in seminaries and houses of religious may be thoroughly influenced by the spirit of the liturgy.
