The Throne, Baptism and the Roman Suppression of Alexandrian Christianity

I sometimes think that the world has been so infected by the American evangelical heresies that they have lost sight of the original Christian mysteries. I am fixated on two absolutely fundamental elements that I am sure were present in the Alexandrian Church of St. Mark during the original baptism ritual - the throne and the baptismal pool. I can't help but think that they were used to ritually re-create the crossing of the ancient Israelites through the sea on the eighth day.

Here is only one of many references to at least part of the original puzzle:

Nor is it without reason that baptism is said to be in the presence of the throne, lest heretics believe that they possess this or can bestow this outside [the church] in the presence of the throne just as we read what was said to Moses, "This is place is near to me" [Ex. 33:21] or as God himself exhorted in Deuteronomy "In the which the Lord your God chooses, to make his name present there." [Deut 14:23](Primasius Commentary on the Apocalypse 4.4 - 6)

My readers can look up these passages themselves. They relate to instances where Moses and the Israelites saw God riding through the air in the throne.

Yet the question of all questions is WHY DOESN'T CHRISTIANITY EVER REFERENCE THE ORIGINAL CONTEXT WHICH SERVED AS THE BASIS TO CHRISTIAN BAPTISM - i.e. the crossing of the sea (cf 1 Cor chapter 10)?

Ah, my Christian friends this is what they have kept from you for centuries. If you knew the traditions of my people you would understand the context of your own religion and why Epiphanius lists the 'Stratiotics' i.e. 'soldiers' as one of the names of those who emerge from the baptismal waters?

Let me tell you a story that was still known to Philo (VM 1.170. 172) and Josephus (AJ II. 321, 326) that Israel was unarmed when entering the waters but after crossing they received the arms of the drowned Egyptians.

Don't you see? There was a reason why the Imperial masters smelled something 'fishy' about this mystery religion in Alexandria. When the Apostle connected the central rite of the new faith to a moment when the Israelites emerged with weapons and armor from their wondrous experience it seemed to have 'seditious' characteristics.

Just read what survives of Celsus' report in Origen Against Celsus Book Eight.

I think the emergence 'stratiotics' from the baptismal waters was the issue for the Roman authorities. I think that it was PERCEIVED to have been responsible for the Alexandrian rebellion of 172 CE and the justification for all subsequent Imperial persecutions in Alexandria in the third century.

Why else do you think that Origen had to respond to a half century old report about Christian practices in the first place?
