Christ arose and defeated Satan. He is the victor. He has given His revelation to man for this Messianic Age and has preserved it within the Body He established here on earth. He will always be the victor and man cannot change His revelation.
I noticed your source Only picked a few of the Church Fathers, but never stated what the Church held. The Church never depended on men to interpret or impose their views or theories upon the Church. If they were faithful to the understanding and teachings of the Church they were accepted as authentic messengers. However, if they went astray they were declared heretical which is the case here.
Protestants make two major errors. First they assume the early Church got everything from scripture as per a Bible as modern day men do. The Church has never been sola scriptura. Secondly, they assume that man has authority over God's revelation to man. The Holy Spirit NEVER gave to individual men any authority over His revelation including scripture.
Consequently they interpret Church Fathers as they do scripture. They impose their own personal authority and interpret it to fit their own theories. You can quote Church Fathers over the last 2000 years who have written on every false teaching ever devised by man. If you want to support Universalism use Origin, yet the Church never held this view. If you want to support that Christ was not God, just use Nestorius. I can do this with every false teaching because they all originated within the Church. Paul was even more concerned about the wolves from within than from without. Outside theories are quite easy to determine.
Protestants have no authority except their own personal intellect and ability to deduce whatever they think scripture might mean. Consequently we have thousands of interpretations, all of equal value because it is based solely on someone's best guess and opinion or worse accept one of the false teachings that has been declared heretical centuries ago.
My link refuted your sweeping statement,
The early Church never was premil.
I only had quotes from the Church Fathers because it showed your statement false.
I hold to Sola Scriptura, yes, and OT Scripture has oodles of Scriptures pointing to a time of bliss after Christ's 2nd coming.
After 40 days of being taught directly by the resurrected Christ, the disciples asked their Lord a question that revealed a pre-mill expectancy...
"So when they had come together, they asked him, "Lord, will you at this time restore the kingdom to Israel?" (Act 1:6)
Christ had come back from the dead and they were expecting perhaps now would be the time Jesus would set up His Kingdom.
Did Jesus tell them, "Look guys, I have been teaching you over 3 years and you still don't get it? Don't you know, from here on out it's all 'spiritual'? " Nope, all He said was, "It is not for you to know times or seasons that the Father has fixed by his own authority." In other words, no rebuke, no denial of a coming physical Kingdom.
Then of course you have this problem. All the prophecies up to that point from the OT were physically fulfilled, why wouldn't one expect the remaining prophecies to be physically fulfilled?
