Chapter 14 — Part I — Chrismation
Section 308. Q. Is this Sacrament mentioned in holy Scripture? A. The inward grace of this Sacrament is spoken of by the Apostle John, as follows: But ye have an unction from the Holy One, and ye know all things. And the anointing which ye have received of him abideth in you, and ye need not that any man teach you; but as the same anointing teacheth you of all things, and is truth, and is no lie; and even as it hath taught you, abide therein. 1 John ii. 20, 27. In like manner the Apostle Paul also says: Now he which stablisheth us with you in Christ, and hath anointed us, is God; who hath also sealed us, and given the earnest of the Spirit in our hearts. 2 Cor. i. 21, 22. Hence are taken the words pronounced at the Unction: The seal of the gift of the Holy Ghost.
