Mysteries revealed by God are truths above the capacity of human reason, but they are not absurd. They are not against reason; they are above reason. If words cannot convey their full sense, no one can prove them to be nonsense. Whatever reason can urge against their truth, reason itself can refute. But reason cannot positively explain their full significance. As a matter of fact, far from being absurd, mysteries are the opposite. The absurd is evidence of the false. But mysteries revealed by God are merely the grandeur of truth itself. They simply bring out the fact that truth is a much greater thing than the small particles of it which the human mind is able to grasp.
No. It presupposes the exercise of reason. It is reasonable to believe what God Himself says of Himself and of His purposes. It is quite reasonable, where we can't see clearly, to accept the authority of God who sees all.
God Himself is not obscure. The trouble lies in our own limitations and in our lack of capacity to understand Him completely. But that does not say that we cannot know that He exists, and that we cannot know quite a lot about Him. Reason, if developed, admits an infinity of things beyond it. If it hasn't got that far it has scarcely commenced work.
Granted a revelation of supernatural truth, there is bound to be some obscurity for us. I say for us, because these truths are not obscure in themselves. God sees their full significance as clearly as you see the noonday sun. But the human mind lacks the capacity to see their full significance just as the human eye cannot see infra-red or ultra-violet light rays. By other means we are sure of the reality of these rays. And whilst human reason cannot see for itself that the Trinity, for example, is a fact, by knowledge of God's revelation we are sure that it is a fact.
