The first interaction is between Her and the Third Person of the Trinity; by His action She becomes capable of giving birth to form. Then is revealed the Second Person, who clothes Himself in the material thus provided, and thus become the Mediator, linking in His own Person Spirit and Matter, the Archetype of all forms. Only through Him does the First Person become revealed, as the Father of all Spirits.
It is now possible to see why the Second Person of the Trinity of Spirit is ever dual; He is the One who clothes Himself in Matter, in whom the twin-halves of Deity appear in union, not as one. Hence also is He Wisdom; for Wisdom on the side of Spirit is the Pure Reason that knows itself as the One Self and knows all things in that Self, and on the side of Matter it is Love, drawing the infinite diversity of forms together, and making each form a unit, not a mere heap of particles--the principle of attraction which holds the worlds and all in them in a perfect order and balance. This is the Wisdom which is spoken of as "mightily and sweetly ordering all things,"[272] which sustains and preserves the universe.
In the world-symbols, found in every religion, the Point--that which has position only--has been taken as a symbol of the First Person in the Trinity. On this symbol St. Clement of Alexandria remarks that we abstract from a body its properties, then depth, then breadth, then length; "the point which remains is a unit, so to speak, having position; from which if we abstract position, there is the conception of unity."[273] He shines out, as it were, from the infinite Darkness, a Point of Light, the centre of a future universe, a Unit, in whom all exists inseparate; the matter which is to form the universe, the field of His work, is marked out by the backward and forward vibration of the Point in every direction, a vast sphere, limited by His Will, His Power. This is the making of "the earth by His Power," spoken of by Jeremiah.[274] Thus the full symbol is a Point within a sphere, represented usually as a Point within a circle. The Second Person is represented by a Line, a diameter of this circle, a single complete vibration of the Point, and this Line is equally in every direction within the sphere; this Line dividing the circle in twain signifies also His duality, that in Him Matter and Spirit--a unity in the First Person--are visibly two, though in union. The Third Person is represented by a Cross formed by two diameters at right angles to each other within the circle, the second line of the Cross separating the upper part of the circle from the lower. This is the Greek Cross.[275]
