The relationship between science and religion are not restricted to the present day, tracing the emergence of so-called modern science in the sixteenth century. An important chapter of this history is the publication of the book The Origin of Species by Charles Darwin in 1859. After 150 years of its publication, we live in a world no less religious. Therefore, we assume that the biology teacher who professes a Christian religious faith deals with two different social constructs: religion and science. Thus, from a pluralistic conception of truth and a proposal for intercultural education based on the concept of tolerance, we investigated the conflicts and arrangements that biology teachers who profess a Christian faith find between creationism and evolution in a world that is both religious and secular. For this, we did semi-structured interviews with ten teachers and analyze the content of their speech. It was shown that the teachers accept the biological evolution, but deny the chance as an important step in this process. Instead, they believe that God drives the evolution. The teachers recognize the importance of evolution to biology, but are divided over the teaching of creationism. We also point that, based on the reference literature and the statements of the subjects of research, a proposal for intercultural education based on tolerance can help solving conflicts involving religion and science in the classroom.
