It is important that they know that they are uniting themselves in marriage as persons baptized in Christ, and that they should behave in conformity to the Holy Spirit in their family life. Thus it is right that future spouses dispose themselves for the celebration of marriage so that it may be valid, worthy and fruitful, by receiving the sacrament of Penance (cf. Catechism of the Catholic Church, n. 1622). The liturgical preparation for the sacrament of Marriage should make the most of the elements of ritual that are currently available. To indicate a clearer relationship between the nuptial sacrament and the paschal mystery, the celebration of marriage is normally set within the celebration of the Eucharist.
