For the vast majority, Divine Knowledge is only accessible through faith, and this is why all great religions are dogmatic, which is to say that they translate metaphysical knowledge into articles of faith, which adapts them to a certain mentality and concretizes them and in this way relativizes them so that they can be accepted in the minds of believers. But again, to accept articles of faith is not to participate in the Divine Knowledge.
In other words, the religions cloth the transcendent in so many secondary forms so that they may be obtained by those to whom they would otherwise be invisible. This is exoterism. Esoterism, which always pertains to metaphysics, takes the essences as its starting point, and so it goes beyond the various religious forms without contradicting them.
