If objectivity and logic were the only bases for religion, then would there be any need for revelation? Clearly, man possessed these abilities before revelation. The need for revelation is that logic and objectivity of men can lead to more than one result, given the perversive influences of psychology and culture.

But on the other hand, we are encouraged to use our intellect by this same revelation. It is revelation & tradition informed by and interpreted with objectivity and logic that rings most true. This way, we pursue the overarching aims and objectives outlined by revelation in an effective manner. Revelation contains arguments instructing us to appeal not to our own logic first, but to the learned. They possess superior knowledge, aided and augmented by skills of reason & logic.

We all have had this experience: One logically works through a problem arriving at a confident answer, only to find out about a variable they did not consider, a constraint unimagined, or just a silly mistake. This is why we are under an obligation to root out and discover these contextual factors... making appeal to our own logic a final step of ascertaining a difficult religious question rather than an initial one.
