In
Eastern Christianity all three sacraments are usually administered at the same time, even in the case of infants. In the
Latin Church and other Western denominations, the rite of
infant baptism was developed for use with babies. In these traditions the
Eucharist and
Confirmation are postponed until the child achieves the age of self-awareness. Adults are normally baptized after enrollment as a
catechumen, either formally, as in the
Latin Church, or more informally, as in some Eastern Catholic Churches. In his apostolic constitution
Divinae consortium naturae on the sacrament of Confirmation,
Pope Paul VI declared: "The sharing in the divine nature given to men through the grace of Christ bears a certain likeness to the origin, development, and nourishing of natural life. The faithful are born anew by Baptism, strengthened by the sacrament of Confirmation, and receive in the Eucharist the food of eternal life." ==Celebration==
