Nobody is claiming Augustine held to Reformed theology. I have zero problem with Warfield's quote. It agrees with what I have been taught and read. The claim was a historical precedent for Reformed theology *regarding perseverance*. Is it a completely developed doctrine in Augustine, formulated precisely without any contradiction in any of his writings? I doubt it. But as they say, "Not even Augustine has read all of Augustine." Still, you can't read what I just quoted and not see at least the seeds of the doctrine in his teaching, not to mention the Scripture he cites. Doctrine develops over time. Contradictions are identified and resolved in the midst of controversy.
