But while I bring out by these proofs the truths of Scripture, and set forth briefly and compendiously things which are stated in various ways, do thou also attend to them with patience, and not deem them prolix; taking this into account, that proofs [of the things which are] contained in the Scriptures cannot be shown except from the Scriptures themselves.
Irenaeus of Lyons
Against Heresies, Book III
Chapter XII
