Man, created in the divine image, is male and female; and these two are one. And their united existence, deriving a new power from their union, multiplies and images itself in a third, which is also a part of itself. It is man, therefore, in his threefold nature, — the father, the mother, and the child,— the beautiful trinity of the family, and yet so constituted that in man's unfallen state it would never have suggested the idea of a weakened or discordant unity, — which may be regarded as the earthly representation, the visible, though dim, shadowing forth of the divine personalities existing in the unity of the Godhead. The original type is in the infinite; but it is reproduced and reflected with greater or less degrees of distinctness in all orders of moral beings.
