8 Thus my mind, full of these results which by its own reflection and the teaching of Scripture it had attained, rested with assurance, as on some peaceful watchtower, upon that glorious conclusion, recognising that its true nature made it capable of one homage to its Creator, and of none other, whether greater or less; the homage namely of conviction that His is a greatness too vast for our comprehension but not for our faith. For a reasonable faith is akin to reason and accepts its aid, even though that same reason cannot cope with the vastness of eternal Omnipotence.
