2. _Yet every truly living Unity is constituted in Multiplicity._ Now in all this there is a most subtle mixture of truth and of error. It is profoundly true that all that _is_ at all, still more all personality, and hence above all God, the Spirit of spirits is, just in that proportion, profoundly mysteriously One, with a Unity which all our best thinking can only distantly and analogously represent. And all religion will ever, in proportion as it is vigorous and pure, thirst after an ever-increasing Unification, will long to be one and to give itself to the One,--to follow naked the naked Jesus. Yet all the history of human thought and all the actual experience of each one of us prove that this Unity can be apprehended and developed, by and within our poor human selves, only in proportion as we carefully persist in stopping at the point where it can most thoroughly organize and harmonize the largest possible multiplicity of various facts and forces. No doubt the living soul is not a whole made up of separate parts; still less is God made up of parts. Yet we cannot apprehend this Unity of God except in multiplicity of some sort; nor can we ourselves become rightly one, except through being in a true sense many, and very many, as well. Indeed the Christian Faith insists that there is something most real actually corresponding to this our conception of multiplicity even and especially in God Himself. For it as emphatically bids us think of Him as in one sense a Trinity as in another a Unity. And it is one of the oldest and most universal of Christian approaches to this mystery, to conceive it under the analogy of the three powers of the soul. God the Father and Creator is conceived as corresponding to the sense-perception and Imagination, to Memory-power; God the Son and Redeemer, as the Logos, to our reason; and God the Holy Spirit, as corresponding to the effective-volitional force within us; and then we are bidden to remember that, as in ourselves these three powers are all united in One personality, so in God the three Persons are united in One substance and nature. Even the supremely and ineffably simple Godhead is not, then, a mere, undifferentiated One.
