Chapter 16 — Part II: The Sacraments — Baptism
Section 69. Infants Receive The Graces Of Baptism — It may not be doubted that in Baptism infants receive the mysterious gifts of faith. Not that they believe with the assent of the mind, but they are established in the faith of their parents, if the parents profess the true faith; if not--to use the words of St. Augustine--then in that of the universal society of the saints; for they are rightly said to be presented for Baptism by all those to whom their initiation in that sacred rite is a source of joy, and by whose charity they are united to the communion of the Holy Ghost.
