Roman Recenstion (Osiris & Horus to Jesus)

A visual overview of how, amid the Roman recension, the Egyptian god Osiris was split three ways into: Jesus Crucified, God the Father, and Lazarus (see: Raising of Lazarus); Anubis became John the Baptist; and Horus became Jesus the infant born to a virgin Mary (see: Isis), in short.

In recensions, Roman recension refers to the making of the state religion of Rome, from 30BC to 800 AD, namely Christianity, from the predominate religious cultural milieu, the Osiris-Horus theology, predominately; and the destruction of all alternative forms of religion therein, e.g. Epicurean theology, Stoic theology, etc..

Overview
In the Roman period, following the Alexandrian recension (322-30BC), there seems to have been first a "Roman redaction" (69-96AD), during which time the then-prevalent recensions were morphed into a crude Christ-centric theology, based on Osiris myth, which was followed by a second Roman recension, culminating in the Nicene council (325AD), and the 692 ruling, by emperor Justinian II, that the image of "Jesus on the cross" should superseded that of the "lamb", as the icon of the new Christian religion.

The following is a depiction of the late stage of the Roman recension, showing a Roman citizen or worker destroying a pagan goddess statue:

a process that began, predominately, in 381, when Theodosius I ordered the Christian persecution of paganism (Ѻ), which continued (Ѻ) up until the fall of the Roman empire in circa 450.

In 1770, Baron d'Holbach, in his Critical History of Jesus Christ: a Rational Analysis of the Gospels, summarizes the Nicene recension, by parodying the fact that it involved some 50 source documents (only four of which were kept) and 318 bishops (of numerous languages and religions).

In 2012, Joseph Atwill, author of Caesar’s Messiah: the Roman Conspiracy to Invent Jesus (2005), in his 2012 documentary on the same subject, argued that the modern version of the Jesus figure was invented by the Caesars or Flavian dynasty (69-96AD) (Ѻ), and therein seems to give a decent summary of an aspect of the “first Roman redaction”.

Quotes
The following are related quotes:

“The conduct of Roman religion was managed by the politicians. The senate was endowed with supreme authority in all matters religious. They delegated decisions to the four main priesthoods, the ‘pontifices’, i.e. the advisory board of priests who assisted the magistrates in their sacra functions, the ‘augurs’, the quindecimviri sacris faciundis (fifteen men in charge of the ritual who were custodians of the Sibylline books, and the septemviri epunoum (the seven in charge of feasts), but the individuals appointed to these offices were not a priestly caste, but men active in public affairs.”
