**Church Fathers** Those viewed as Church Fathers today are because one Christian faction won. Had the Gnostics won, we'd be reading Marcion, Cerinthus, Basilides, Simon Magus and others. If the Monarchians had won Theodotus and Paul of Samosata would be studied in the seminaries. If Seballianism (Modalism) had become the orthodox belief, Sabellius, Peareus, Noetus and Epigones would be among our Church Fathers.
The Church Fathers disagreed with one another, one reason why such great minds as Tertullian and Origen lost their status. I don't recall the various points (it's been some years since I read up on all this), but as I remember Origen, for example, said that the Bible could not be taken literally in many places, as it was immoral and non-believable at those spots, so he treated much of scripture as allegorical. So he was dropped from the approved list of Church Fathers. Personally I found the works of Origen especially provocative and interesting.
**Pagan influences**. I don't want to overstate things, but there appear to be many pagan influences in Christianity, many of them adopted from mystery religions or Greco-Roman polytheism. I forgot the number, but a variety of gods were born at the time of the winter equinox, on or about Dec. 25. There seems to be evidence that Sun worship may have influenced the moving of the Sabbath from the 7th to the 1st day - Sunday. Then we have Moonday - and every other day is named after a pagan god or goddess. Same with the planets. And we could go on and on. Lots of feast days fall today on days that already were observed for somewhat similar reasons in one or another pagan faith.
This doesn't invalidate Christianity of course, but it should make us aware that some doctrines and rites may have been influenced by the ethos of the time. Frankly, I think it isn't obvious that the Pope became the undisputed head of the western church until the time of Gregory the Great (590 AD?). Before that evidence suggests that the various bishops zealously guarded their diocese from outside control, even from Rome. Before that Constantine had moved the seat of the empire to Constantinople and synods and dioceses.in the East looked to that city as the seat of ecclesiatical authority, although with more of an emphasis on 'first among equals' which was lost with the growing dominance of the Roman bishop in the west.
So much more to say, but is it worth my time? I doubt it. Tribalism is strong, and those who want to believe something will believe it whatever.... And that's okay with me. My problem is that I have great sympathy for independent thinkers within the church, people of intelligence and curiosity who find it hard to give their assent to everything that Catholics are supposed to believe. So many have been lost. I think that there should be more room in the church for different viewpoints. For example, I think priests should have the freedom to marry, but Pope John Paul II, as I recall, took that issue off the table. not even to be discussed. I personally think it's not important whether Mary was a perpetual virgin or that she and Joseph had other children - no sin in that, actually a more attractive Holy Family in my view. You can get an annulment (I believe) if a couple doesn't have normal marital relations.
Oh, well, off to other duties and concerns. God bless everybody.
