to the great foundation truth of the Old
Testament that God is One. The world in which Christianity found itself
had a host of deities--a god for the sea and another for the wind, a god
of the hearth and a god of the empire, and so on. Today it is only too
easy to obey one motive in the home and another in one's business, to
follow one principle in private life and another in national life, and
to be polytheists again. Christian faith insists that "there is one God,
the Father, of whom are all things and we unto Him." We adore One who is
Christlike love, and we will serve no other. We trust Christlike love as
the divine basis for a happy family life, and also for successful
commerce, for statesmanlike international dealings, for the effective
treatment of every political and social question. The inspirations that
come to us from a glorious piece of music or from an heroic act of
self-sacrifice, from some new discovery or from a novel sensitiveness of
conscience, are all inspirations from the one God. At every moment and
in every situation we must keep the same fundamental attitude towards
life--trustful, hopeful, serving--because in every experience, bitter or
sweet, we are always in touch with the one Lord of all, our Christlike
Father.

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 C
