Man created God in his own image.

My only wish isto transform friends of God into friends of man, believers into thinkers, devotees of prayer into devotees of work, candidates for the hereafter into students of the world, Christians who, by their own procession and admission, are half animal, half angel into persons, into whole persons.

If therefore my work is negative, irreligious, atheistic, let it be remembered that atheism — at least in the sense of this work — is the secret of religion itself; that religion itself, not indeed on the surface, but fundamentally, not in intention or according to its own supposition, but in its heart, in its essence, believes in nothing else than the truth and divinity of human nature.

Man created God in his own image.

The task of the modern era was the realization and humanization of God – the transformation and dissolution of theology into anthropology.

In the consciousness of the infinite, the conscious subject has for his object the infinity of his own nature.

Theology is Anthropology... [T]he distinction which is made, or rather supposed to be made, between the theological and anthropological predicates resolves itself into an absurdity.
