Chapter 16 — Part II: The Sacraments — Baptism
Section 55. Duties Of Sponsors — The faithful are also to be taught the duty of sponsors; for such is the negligence with which this office is treated in the Church that only the bare name of the function remains, while none seem to have the least idea of its sanctity. Let all sponsors, then, at all times recollect that they are strictly bound by this law to exercise a constant vigilance over their spiritual children, and carefully to instruct them in the maxims of a Christian life; so that these may show themselves throughout life to be what their sponsors promised in the solemn ceremony.
