Here are the proofs from the New Testament. The first proof the Theology finds in Christ’s conversation with his disciples: Believe me that I am in the Father, and the Father in me (John xiv. 11); and whatsoever ye shall ask in my name, that will I do, that the Father may be glorified in the Son (John xiv. 13). From the fact that Jesus Christ calls himself the Son of the Father, God, just as he taught all men to call themselves the sons of God, it is argued that Jesus Christ is a second person of God. The author says: “Here evidently two persons of the Holy Trinity, the Father and the Son, are distinguished.” (p. 175).
The second proof is taken from the passage where Jesus Christ says to his disciples, If ye love me, keep my commandments. And I will pray the Father, he shall give you another Comforter, that he may abide with you for ever; even the Spirit of truth; whom the world cannot receive (John xiv. 15-17). The last verse is not written out, but instead of it the continuation is taken from verse 26 of the same chapter: but the Comforter, which is the Holy Ghost, whom the Father will send in my name, he shall teach you all things, and bring all things to your remembrance, whatsoever I have said unto you. (p. 175.)
From this it is concluded:
“Here all three persons of the Most Holy Trinity are distinguished, namely, as persons: the Son, who speaks of himself: I will pray,—the Father: I will pray the Father,—the Holy Ghost, who is called another Comforter, consequently distinct from the Father; and he will be sent to take the place of the Son with the apostles and to teach them everything; consequently, he is just such a person as the Son.” (p. 175.)
Because the paraclete, that is, the comforter, whom Christ promises his disciples after his death, is once during that conversation called the Holy Ghost, it is taken as a proof that Christ in this conversation revealed
