Abstract
Bringing together perspectives is rarely an easy task. By assembling researchers from cognitive and cultural traditions to discuss their reciprocal research in the field of psychology of religion, we thought that we will end up with an ecumenical conclusion, everyone being convinced that the other perspective will enrich her or his approach in the future. In this introduction, our objective is to show that it was not exactly the case and, by writing a two-voices introduction, to understand why we were eventually not so sure that we were all studying the same object.
