It may be that the unlettered Catholic cannot cope with these arguments in detail; cannot tell whether it is that the facts are untrue, or that the logic is unsound. But he well knows that the grace of faith was meant for all, though all have not the learning or the power to unravel the sophistry of error. He may, therefore, in safety cling fast to that Church which is "the pillar and the ground of Truth", and pass by unheeded the eloquence and the subtlety of those who would fain draw him into the arena of controversy. Conscious that he has truth upon his side, he has nothing to fear from the progress of human learning. New sciences may, in their infant struggles, seem for a time to clash with that Revelation which, in God's design, they were meant to confirm, to illustrate, and to adorn. But he may calmly await the issue of the conflict, with a firm conviction that, in the end, the cause of truth must triumph; that, when proof shall have taken the place of conjecture, when theories shall have been tested by facts, when doubt and uncertainty shall have been dispelled by new discoveries, science will then prove to be, as she has ever been, not the enemy of religion, but her friend, and faithful ally. It is not fit, however, that all should remain idle spectators of the struggle between science and Revelation. There are many whose intellectual acquirements, and whose opportunities, will permit them to gird on their armour, and to go forth to battle in the cause of truth. The rich treasures of learning and science which they have amassed cannot be better employed, than for the ornament and defence of the Church of God. Such men, if we may borrow a beautiful figure from the early Fathers, are like the Hebrews of old, who, having carried away the precious spoils of Egypt, laid them, with a profuse generosity, at the feet of Moses for the service of the Tabernacle. As for ourselves, we are sensible that, from our scanty means, we have little to offer. But, in the temple of God, each one may contribute according to the measure of his abilities. While others, therefore, bring their gold, and their silver, and their precious stones, we may humbly venture to make our simple offering at least of hair and skins.[11]
