170. (3) Before the world was created this Trinity was not; but after creation, when God became incarnate, it was provided and brought about, and then in the Lord God the Redeemer and Savior Jesus Christ. In the Christian church at the present day a Divine trinity existing before the creation of the world is acknowledged; that is, that Jehovah God begat a Son from eternity, and that the Holy Spirit then went forth from both, and that each of these three is by Himself or singly God, because each is one person subsisting of Himself. But as this is incomprehensible to all reason it is called a mystery, which can be penetrated only in this way-that these three have one Divine essence, by which is meant eternity, immensity, omnipotence, and thus an equal Divinity, glory, and majesty. But that this trinity is a trinity of three Gods, and therefore in no sense a Divine trinity, will be shown in what follows: while from all that precedes it is evident that the trinity (which is also a trinity of Father, Son, and Holy Spirit) which was provided and brought about when God became incarnate, thus after the world was created, is a Divine trinity, because it is a trinity in one God. This divine trinity is in the Lord God the Redeemer and Savior Jesus Christ, because the three essentials of the one God, which constitute one essence, are in Him. That in Him (as Paul says) dwelleth all the fullness of Divinity is evident also from the words of the Lord Himself, that all things of the Father are His, and that the Holy Spirit speaks from Him, and not of itself; and finally, that when He arose He took from the sepulchre His whole human body, both the flesh and the bones (Matt. 28:1-8; Mark 16:5, 6; Luke 24:1-3; John 20:11-15), unlike any other man; of which He bore living witness to His disciples, saying:
Behold My hands and My feet, that it is I Myself handle Me and see; for a spirit hath not flesh and bones as ye see Me have (Luke 24:39).
From this every man may be convinced, if he will, that the Lord's humanity is Divine; consequently, that in Him God is Man and Man is God.
