To what extent is faith a legitimate basis for knowledge claims, in religion and different areas of knowledge?

Let us take all knowledge systems to be a vast intricate structure. Faith is the foundation of this structure, because certain fundamental assumptions are made on which all knowledge systems are based. We use reason to continuously build upon this foundation the beautiful and complex structure of knowledge. Without these fundamental assumptions or axioms which cannot be justified nor refuted by reason, the structure of knowledge would collapse and there would be no way to …

…of knowledge cannot be built; and since faith is not universal, a unified system of knowledge that is not paradoxical cannot possibly be based on it. 1. reason: with the same premises, if correct logic is used, the same conclusion is reached. Not so with other ways of knowing: perception, language, emotion. Same with faith. 2. other areas of knowledge are not unified the foundation must be reinforced by 3. other areas of knowledge and must thus evolve.
