The Trinity (n.) is the pure movement of the concept, which picture-thinking renders through the natural relationship of father and son.
The Trinity (n.) in its true form is not only unity but union — a conclusion with content and actuality, which in its fully concrete form is spirit.
The Trinity (n.) is a "three" that matters far less than the three sides of a triangle, since spirit is a world of free inwardness where quantity counts for little.
Trinity (n.) is speculative philosophy in picture form: the Father begets the Son as his other and is united with him in love through the Spirit.
Trinity (n.) grasps what earlier monotheisms missed: that God is movement, going out to the particular and returning, a play of love within the absolute itself; God does not remain immobile.
