You are right, Steele must have been postmillennialist. I didn’t read your link close enough.
When I said ECF, I meant the Ante-Nicene Fathers. I have the full set, which I have had for about 30 years. The Origen-Augustine apostasy had fully set in by the 500’s and 600’s you speak of, concluding with the Papacy. I consider their system, including their millennial doctrine, false. Yours, and Steele’s, eschatology a derivation of theirs.
The ECF I speak of were indeed to a man premillennialist. Their eschatology preceded that of Augustine and the Papacy. The ECF I speak of, being closer to what was handed down from the apostles, we would expect more closely to reflect the true eschatology. Known today as Historic Premillennialism. Which, as I pointed out in my previous post, was not dispensational nor pretrib.
Thankfully, even the Apostolic Fathers recognized that belief in ‘historic premillennialism’ wasn’t a test of orthodoxy. After all, even Justin Martyr acknowledged that “many who belong to the pure and pious faith, and are true Christians, think otherwise” about historic premillennialism, even in his own time period.
