Are you suggesting the UPCI doctrine of oneness is heretical?
We are here to debate, not cast out personal judgements. If you can't back up your doctrine with scripture then you should not nreply
The Orthodox, Eastern and Oriental, along with the Catholics and the Assyrian Church of the East, who together are being martyred in Iraq, Syria, Egypt, and Libya, reject Sola Scriptura. For us, the Bible is part of Holy Tradition. The New Testament was written by the Church, for the Church, as evinced by the fact that the books you find in your New Testament were first assembled into a definitive canon by St. Athansius, the most ardent champion of the Nicene Creed and of the Holy Trinity.
So I will argue against your position Biblically, from a different angle. If you wish to be Sabellian, you should not base your argument on the canon of New Testament books compiled by St. Athanasius who was Trinitarian. Rather, you should invoke scriptures Athansius and the other fathers of the early Church deemed heretical, which lend more support to the Sabellian position. Or, to be brutally honest, write your own.
Because there is no historical evidence at all to suggest that the books that comprise the New Testament were co-opted by Trinitarians.
One of the earliest critics of Sabellianism was St. Irenaeus. Irenaeus was a disciple of Polycarp, who in turn was a disciple of St. John the Beloved Disciple, who was the last of the apostles to die, around AD 90. And St. Irenaeus espouses a theology that almost precisely aligns with the modern beliefs of the Orthodox Church, the one difference being he was premillenial, whereas the consensus shifted towards an amillenial interpretation.
But all of the beliefs, and even the worship practices, of the Orthodox, and the Assyrians (and the Roman Catholics before the Great Schism, and liturgically, before Vatican II), can be traced to the Apostolic fathers like Ss. Ignatius, Polycarp, Clement, Justin Martyr and Dionysius the Aereopagite. And it beggars belief to suggest that these men, who were primarily responsible for the propagation of Christianity after the death of the Twelve and the Seventy, would intentionally or unwittingly distort the teachings of the Apostles. But people like Simon Magus, Marcion, Sabellius, Valentinus, Montanus and Arius started cropping up immediately, Simon Magus almost right after Pentecost, and fought relentlessly to corrupt the teachings of the Church.
But the four ancient communions who embraced Nicea, to wit, the Eastern and Oriental Orthodox, the Assyrian Church of the East, and the Roman Catholic Church, are still here, whereas the various ancient non-orthodox sects are all extinct. The last surviving one, the Paulicans, lingered on in the mountains of Armenia until the 19th century, when the Armenian bishops successfully evangelized them to Orthodoxy.
