Roman Catechism 17.14

Chapter 17 — Part II: The Sacraments — Confirmation

Section 14. The Remote Matter Of Confirmation Is Chrism — That such is the matter of this Sacrament the holy Church and her Councils have always taught; and the same doctrine has been handed-down to us by St. Denis and by many other Fathers of the gravest authority, particularly by Pope Fabian,' who testifies that the Apostles received the composition of chrism from our Lord and transmitted it to us.
