This study examines the purifying function of philosophy in the examination of religion, specifically Christianity as a worldview. Philosophy's role is not to disrupt religion, but to deepen, consolidate, and organize it, especially during times of faith crisis. The author points out two main errors leading to disagreement with religion: insufficient understanding and the tendency to view religion as exclusively an emotional matter. It is emphasized that every religion must evolve to remain relevant, and its dogmatics must align with reason and science. Dogmatics should not contain assertions contradicting scientific knowledge or assertions that belong within science. It must be built on the foundations of human thought and logical norms to become part of a probable worldview. The philosophy of religion, in this case Christianity, should be the most credible theory and the sole correct worldview, derivable from purely philosophical principles, although faith itself cannot be induced in this manner.
