"Human salvation demands the divine disclosure of truths surpassing reason," St. Thomas Aquinas. Reason avails upon ideas within grasp of our human intellect. Salvation comes from God extending Himself into and towards us to our limitations, but He is not bounded within the limitations of our own minds. Therefore, the full truth of human salvation goes beyond the limitations of our human reasoning, as it is grounded in God.
