The doctrine of the Trinity
We have sufficiently spoken of the Father and of the Son, so far as was possible for us to see through this glass and in this enigma. We must now treat of the Holy Spirit, so far as by God’s gift it is permitted to see Him. And the Holy Spirit, according to the Holy Scriptures, is neither of the Father alone, nor of the Son alone, but of both; and so intimates to us a mutual love, wherewith the Father and the Son reciprocally love one another. But the language of the Word of God, in order to exercise us, has caused those things to be sought into with the greater zeal, which do not lie on the surface, but are to be scrutinized in hidden depths, and to be drawn out from thence. The Scriptures, accordingly, have not said, The Holy Spirit is Love. If they had said so, they would have done away with no small part of this inquiry. But they have said, God is love; so that it is uncertain and remains to be inquired whether God the Father is love, or God the Son, or God the Holy Ghost, or the Trinity itself which is God. For we are not going to say that God is called Love because love itself is a substance worthy of the name of God, but because it is a gift of God, as it is said to God, You are my patience. For this is not said because our patience is God’s substance, but in that He Himself gives it to us; as it is elsewhere read, Since from Him is my patience. For the usage of words itself in Scripture sufficiently refutes this interpretation; for You are my patience is of the same kind as You, Lord, art my hope, and The Lord my God is my mercy, and many like texts. And it is not said, O Lord my love, or, You are my love, or, God my love; but it is said thus, God is love, as it is said, God is a Spirit. And he who does not discern this, must ask understanding from the Lord, not an explanation from us; for we cannot say anything more clearly. Continue reading
All those Catholic expounders of the divine Scriptures, both Old and New, whom I have been able to read, who have written before me concerning the Trinity, Who is God, have purposed to teach, according to the Scriptures, this doctrine, that the Father, and the Son, and the Holy Spirit intimate a divine unity of one and the same substance in an indivisible equality; and therefore that they are not three Gods, but one God: although the Father has begotten the Son, and so He who is the Father is not the Son; and the Son is begotten by the Father, and so He who is the Son is not the Father; and the Holy Spirit is neither the Father nor the Son, but only the Spirit of the Father and of the Son, Himself also co-equal with the Father and the Son, and pertaining to the unity of the Trinity. Yet not that this Trinity was born of the Virgin Mary, and crucified under Pontius Pilate, and buried, and rose again the third day, and ascended into heaven, but only the Son. Nor, again, that this Trinity descended in the form of a dove upon Jesus when He was baptized; nor that, on the day of Pentecost, after the ascension of the Lord, when there came a sound from heaven, as of a rushing mighty wind, the same Trinity sat upon each of them with cloven tongues like as of fire, but only the Holy Spirit. Nor yet that this Trinity said from heaven, You are my Son, whether when He was baptized by John, or when the three disciples were with Him in the mount, or when the voice sounded, saying, I have both glorified it, and will glorify it again; but that it was a word of the Father only, spoken to the Son; although the Father, and the Son, and the Holy Spirit, as they are indivisible, so work indivisibly. This is also my faith, since it is the Catholic faith.
