The article considers the ways of thinking of Science and Christianity in their relationship. The article demonstrates that there are three different aspects in understanding of scientific thinking. The first is based on «dogmatic» tradition of the Scientific Revolution of the seventeenth century. The second considers science in the frame of critical rationality (K. Popper, H. Albert). The third demonstrates the irrational base of science and therefore its closeness to religion. The «ethos» of Scientific and of Christian communities are described in connection with all the three approaches. The article shows that each of these aspects implies the confrontation with the Christian way of thinking.
