On the Sacraments of Initiation

It is common to think that the idea of the Sacraments of Initiation was lost to the Western Church for hundreds of years. I suppose that was true in a way, but not completely. This is from the Treatise on the Admirable Heart of Jesus by St. John Eudes, whose optional memorial is today:

Finally you are one with Jesus as the body is one with the head. You must then have one breath with him, one soul, one life, one will, one mind, one heart, And he must be your breath, heart, love, life, your all. These great gifts in the follower of Christ originate from baptism. They are increased and strengthened through confirmation and making good use of other graces that are given by God. Through the holy eucharist they are brought to perfection.

Sounds a lot like the CCC:

1212 The sacraments of Christian initiation—Baptism, Confirmation, and the Eucharist—lay the foundations of every Christian life. “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. By means of these sacraments of Christian initiation, they thus receive in increasing measure the treasures of the divine life and advance toward the perfection of charity.” [Paul VI, apostolic constitution, Divinae consortium naturae: AAS 63 (1971) 657; cf. RCIA Introduction 1-2.]
