Unless I am utterly mistaken, there is nothing so old as the truth; and the already proved antiquity of the divine writings is so far of use to me, that it leads men more easily to take it in that they are the treasure-source whence all later wisdom has been taken. … What poet or sophist has not drunk at the fountain of the prophets? Thence, accordingly, the philosophers watered their arid minds, so that it is the things they have from us which bring us into comparison with them. For this reason, I imagine, philosophy was banished by certain states … its disciples sought to imitate our doctrines; and ambitious, as I have said, of glory and eloquence alone, if they fell upon anything in the collection of sacred Scriptures which displeased them, in their own peculiar style of research, they perverted it to serve their purpose: for they had no adequate faith in their divinity to keep them from changing them, nor had they any sufficient understanding of them, either, as being still at the time under veil—even obscure to the Jews themselves, whose peculiar possession they seemed to be. For so, too, if the truth was distinguished by its simplicity, the more on that account the fastidiousness of man, too proud to believe, set to altering it; so that even what they found certain they made uncertain by their admixtures. Finding a simple revelation of God, they proceeded to dispute about Him, not as He had revealed to them, but turned aside to debate about His properties, His nature, His abode. … According to each one’s fancy, He has introduced either something new, or refashioned the old. Nor need we wonder if the speculations of philosophers have perverted the older Scriptures. Some of their brood, with their opinions, have even adulterated our new-given Christian revelation, and corrupted it into a system of philosophic doctrines, and from the one path have struck off many and inexplicable by-roads.
