Religion, at least the Christian, is abstraction from the world; it is essentially inward. The religious man leads a life withdrawn from the world, hidden in God, still, void of worldly joy. He separates himself from the world, not only in the ordinary sense, according to which the renunciation of the world belongs to every true, earnest man, but also in that wider sense which science gives to the word, when it calls itself world-wisdom (welt-weisheit); but he thus separates himself only because God is a being separate from the world, an extra and supramundane being,--i.e., abstractly and philosophically expressed, the non-existence of the world. God, as an extramundane being, is however nothing else than the nature of man withdrawn from the world and concentrated in itself, freed from all worldly ties and entanglements, transporting itself above the world, and positing itself in this condition as a real objective being; or, nothing else than the consciousness of the power to abstract oneself from all that is external, and to live for and with oneself alone, under the form which this power takes in religion, namely, that of a being distinct, apart from man. [44] God as God, as a simple being, is the being absolutely alone, solitary--absolute solitude and self-sufficingness; for that only can be solitary which is self-sufficing. To be able to be solitary is a sign of character and thinking power. Solitude is the want of the thinker, society the want of the heart. We can think alone, but we can love only with another. In love we are dependent, for it is the need of another being; we are independent only in the solitary act of thought. Solitude is self-sufficingness. But from a solitary God the essential need of duality, of love, of community, of the real, completed self-consciousness, of the alter ego, is excluded. This want is therefore satisfied by religion thus: in the still solitude of the Divine Being is placed another, a second, different from God as to personality, but identical with him in essence,--God the Son, in distinction from God the Father. God the Father is I, God the Son Thou. The I is understanding, the Thou love. But love with understanding and understanding with love is mind, and mind is the totality of man as such--the total man. Participated life is alone true, self-satisfying, divine life:--this simple thought, this truth, natural, immanent in man, is the secret, the supernatural mystery of the Trinity. But religion expresses this truth, as it does every other, in an indirect manner, i.e., inversely, for it here makes a general truth into a particular one, the true subject into a predicate, when it says: God is a participated life, a life of love and friendship. The third Person in the Trinity expresses nothing further than the love of the two divine Persons towards each other; it is the unity of the Son and the Father, the idea of community, strangely enough regarded in its turn as a special personal being.
