Joseph Ratzinger warns about a multitude of trials to superficially undertake the subject of religion. In this diverse world of religion, he sees some common points. The first step in the history of religion was to transcend the primitive, moving into myth. Second, most important step, was to leave the myth behind. This leaving is threefold – which is represented by three irreducible shapes of religion: the identity mysticism, the monotheistic revolution and the enlightenment. An expression of the first two are, respectively: the identity mysticism and the personal love mysticism. The fact that religions are affecting each other must not be omitted, either. The place of Christianity in the history of religion – nota bene gained by both, the dialogue with other religions and standing against them – defines standing with the God of faith and the God of the philosophers, and the decisive choice of faith and mind together with the truth and the cult. In his thoughts concerning the dialogue of religions, J. Ratzinger points out two types: the mystical and theist, of the religion. Along them walks as a temptation the pragmatic type, in which the question about the truth is ignored. The result of the dialogue of the religions will not be a unification of all religions. In this dialogue, the truth cannot be ignored. At last, it cannot be forgotten that there is a religio vera, and that it is Christianity.
