Emperor Constantine
Emperor Constantine ruled from 306 - 337 CE. He is the reason -- outside of the holy Messiah himself -- that "the West" is Christian. On his deathbed (following the predominant custom of his day), he was baptized by Eusebius of Nicomedia, a prominent Arian Christian. (The Arians were the followers of Arius, a Berber or Libyan who taught in Alexandria that Jesus was not eternal and was subordinate to God the Father, a non-Trinitarian doctrine much more in harmony with Islam.)
Put plainly, Emperor Constantine was an Arian Christian.
Indeed, Arianism was dominant for much of the 4th century (300s) because it was backed by the Imperial family (Constantine's descendents). It was not until the reign of the staunchly Trinitarian Emperor Theodosius (392 - 395 CE) that Arianism was officially outlawed within the Roman state. Arianism has been branded heresy by all Christendom since that day.
Put plainly, the man who made "the West" Christian was a heretic!
Lucian of Antioch
Lucian (240 - 312 CE) was a Syrian from Samasota (modern Samsat), Syria. He is known as the father of the "Majority Text", the body of writings the Eastern Orthodox Church (Greek & Russian) regards as the purest surviving biblical manuscripts. Taken together, these manuscripts form a complete Orthodox Bible (Old & New Testaments). The long-since-lost Master Copy was, according to tradition, compiled by Lucian.
This "Majority Text" ultimately undergirds the famous "Authorized Version", often called the "King James Version", so-called. (FYI, King James was a rampant Sodomite, and his authorizing the Puritans to produce an official Protestant Bible in England was literally the least he could afford to do at the time.)
This "Authorized Version" is widely hailed as the best modern translation of the Old & New Testaments. (Catholics would argue this point, of course.)
So, we have established that Lucian gave us the best surviving biblical manuscripts in all of ("Western") Christendom.
In particular, he is hailed by the Eastern Orthodox.
And yet Lucian had a very famous pupil -- Arius of Alexandria. In fact, Lucian is widely regarded as the true author of Arius' school of thought! That is, "Arian" Christianity is more properly Lucian Christianity!
Put plainly, Lucian was an Arian Christian.
Put plainly, the man to whom all of Christendom (outside Rome) gratefully looks for its scriptures was also a heretic!
And, what is more, exactly the same flavor of heretic as Emperor Constantine, the man who made "the West" officially Christian.
If you didn't know better, you'd say those Arians couldn't be all that bad! They made us Christian, and they gave us our best bibles! (And, as it happens, their views were much closer to Islam.)
And yet all of Christendom today brands the Arians heretics. False worshippers! Wolves in Sheeps' clothings!
And yet they gave us our faith and our bibles.
Heretics made "the West" Christian and gave "the West" their scriptures.
This is a logical inconsistency, and falls in the "condemned by thine own tongue" category.
