In this Unity Christians have spoken of a Trinity. Paul summing up the blessing of God, speaks of "the grace of our Lord Jesus Christ, and the love of God, and the communion of the Holy Spirit." He says, "through Jesus we have our access in one Spirit unto the Father." He and his fellow believers had been redeemed from selfishness to love, from slavery to freedom; and they accounted for their new life by saying that, through the grace of Jesus, they had come to experience the fatherly love of God, and to find His Spirit binding them in a brotherhood of service for one another and the world. The New Testament goes no further: it states these experiences of Jesus, of God, of the Spirit; but it does not tell us the exact relations of the Three--how God is related to the Spirit, or Jesus distinct and at the same time one with the Father. So acute a thinker as Paul never seems to have worked this out. At one time he compares God's relation to His Spirit to man's relation to his spirit ("Who among men knoweth the things of a man, save the spirit of the man which is in him? even so the things of God none knoweth, save the Spirit of God"); and once he identifies the Spirit with the glorified Christ ("The Lord is the Spirit"). But while Paul and other New Testament writers did not feel the need of thinking out what their threefold experience of God implied as to His Being, later Christians did; and using the terms of the current Greek philosophy, they elaborated the conception of three "Persons" in one Godhead. We have no exact equivalent in English for the Greek word which is translated "person" in this definition. It is not the same as "a person" for that would give us three gods; nor is it something impersonal, a mode or aspect of God. It is something in between a personality and a personification.
