The whole concern of doctrine and its teaching must be directed to the love that never ends. Whether something is proposed for belief, for hope or for action, the love of our Lord mush always be made accessible, so that anyone can see that all the works of perfect Christian virtue spring from love and have no other objective than to arrive at love. CCC#25
"So faith, hope, love remain, these three, but the greatest of these is love." 1Cor 13:13
The Sacraments of Christian Initiation
Let's start at the begining
251. How is Christian initiation brought about?
CCC#1212
CCC#1275
Christian initiation is accomplished by means of the sacraments which establish the foundations of Christian life. The faithful born anew by Baptism are strengthened by Confirmation and are then nourished by the Eucharist.
THE SACRAMENT OF BAPTISM
252. What names are given to the first sacrament of initiation?
CCC#1213-1216
CCC#1276-1277
This sacrament is primarily called Baptism because of the central rite with which it is celebrated. To baptize means to “immerse” in water. The one who is baptized is immersed into the death of Christ and rises with him as a “new creature” (2 Corinthians 5:17). This sacrament is also called the “bath of regeneration and renewal in the Holy Spirit” (Titus 3:5); and it is called “enlightenment” because the baptized becomes “a son of light” (Ephesians 5:8).
