Judeo-Christian Revelation shows not only God, but also a man, and all the reality as well, especially in their relation to God. Therefore, one is allowed to talk about “lay heresies”, that is the wrong understanding of the created reality. The “Christological formula” of Chalcedon stressing the synthesis that takes place “unconfusedly and indivisibly” can help to estimate the degree to which the “new atheism” is a heretical interpretation of reality; it happens when things that are created are “divided” from the Creator, which, in turn, leads to “monophysitic” perception of the world chosen by Richard Dawkins and Christopher Hitchens.
