Chapter 16 — Part II: The Sacraments — Baptism
Section 51. Why Sponsors Are Required At Baptism — In the first instance it should be explained why at Baptism, besides those who administer the Sacrament, godparents and sponsors are also required. The propriety of the practice will at once appear to all if they recollect that Baptism is a spiritual regeneration by which we are born children of God; for of it St. Peter says: As newborn infants, desire the rational milk without guile. As, therefore, every one, after his birth, requires a nurse and instructor by whose assistance and attention he is brought up and formed to learning and useful knowledge, so those, who, by the waters of Baptism, begin to live a spiritual life should be entrusted to the fidelity and prudence of some one from whom they may imbibe the precepts of the Christian religion and may be brought up in all holiness, and thus grow gradually in Christ, until, with the Lord's help, they at length arrive at perfect manhood.
