Chapter 4—Of Efficacious Grace
Section 15—Didymus Alexandrinus. A.D. 370.
Didymus of Alexandria, in his treatise concerning the Holy Spirit, says many things of his grace and power in the sanctification of men. “The Holy Spirit,” says he, “is by the confession of all, the immutable sanctifier, the giver of divine knowledge, and all good things; and that I may speak more briefly, he is subsisting in those good things, which are given by the Lord, according to Matthew 7:11 and Luke 11:13; from whence it appears, that the Holy Spirit is the fullness of the gifts of God, and that those things which are ministered by God do not subsist without him; for all advantages which are received from the grace of the gifts of God flow from this fountain.” And a little after he calls him the giver of sanctification, and says that it is impossible any one should obtain the grace of God si non habeat Spiritum Sanctum, “‘if he has not the Holy Spirit;' in which we prove, that all the gifts of God consist.” And again, says he, “No one ever receives the spiritual blessings of God, nisi praecesserit Spiritus Sanctus, ‘unless the Holy Spirit goes before;' for he that receives the Holy Spirit consequently will have blessings, that is, wisdom and understanding, and the rest; —wisdom and understanding which are in the Holy Spirit are given by God: —God the giver of good things, will give the hope which he has promised, in the power of the Holy Ghost to them that have him.”
