23 In order that all these endeavours and exertions may really prove advantageous to the cause of the Bible, let scholars keep steadfastly to the principles which We have in this Letter laid down. Let them loyally hold that God, the Creator and Ruler of all things, is also the Author of the Scriptures - and that therefore nothing can be proved either by physical science or archaeology which can really contradict the Scriptures. If, then, apparent contradiction be met with, every effort should be made to remove it. Judicious theologians and commentators should be consulted as to what is the true or most probable meaning of the passage in discussion, and the hostile arguments should be carefully weighed. Even if the difficulty is after all not cleared up and the discrepancy seems to remain, the contest must not be abandoned; truth cannot contradict truth, and we may be sure that some mistake has been made either in the interpretation of the sacred words, or in the polemical discussion itself; and if no such mistake can be detected, we must then suspend judgment for the time being. There have been objections without number perseveringly directed against the Scripture for many a long year, which have been proved to be futile and are now never heard of; and not unfrequently interpretations have been placed on certain passages of Scripture (not belonging to the rule of faith or morals) which have been rectified by more careful investigations. As time goes on, mistaken views die and disappear; but "truth remaineth and groweth stronger for ever and ever."(61) Wherefore, as no one should be so presumptuous as to think that he understands the whole of the Scripture, in which St. Augustine himself confessed that there was more that he did not know, than that he knew,(62) so, if he should come upon anything that seems incapable of solution, he must take to heart the cautious rule of the same holy Doctor: "It is better even to be oppressed by unknown but useful signs, than to interpret them uselessly and thus to throw off the yoke only to be caught in the trap of error. "(63)
