Roman Catechism 17.28

Chapter 17 — Part II: The Sacraments — Confirmation

Section 28. All Should Be Confirmed — First, it is necessary to teach that this Sacrament is not so necessary as to be utterly essential to salvation. Although not essential, however, it ought to be omitted by no one, but rather, on the contrary, in a matter so full of holiness through which the divine gifts are so liberally bestowed, the greater care should be taken to avoid all neglect. What God has proposed in common unto all for their sanctification, all should 'likewise most earnestly desire.
