Vestments - Part Deux

Responding more amply to the Question on Vestments:

Nestled away in the mountains between Wicklow and Dublin, between the Sugar Loaf mountains of Killiney Bay on the south side, to the mountains and ridges of Howth Head on the north side, stands the site of an old California style very woke kind of seminary on the banks of the River Tolka, possibly on the actual battle site of the famous and decisive Battle of Clontarf from 1014 AD, where King Brian the King Priam lost his life, and it was at this very woke location where in my youthful days at seminary I first heard those lines about the secular origins of the church vestment, usually worn by a bishop or priest or deacon at solemn occasions; but any expert in the Roman Empire would spot the canard, and tell the reader and questioner that the original inspiration for the Christian vestments was not the toga nor the political senate, but rather it was a religious origin in the vestments and garbs that the Greek in the main priests and priestesses wore to the various temple sacrifices around the Roman Forum and beyond. Greek style vestments were worn by the various priests and priestesses of pagan Rome. Hebrew priests too, those few that survived the bloodletting of the End of the Temple in 70 AD or 820 AUC in the roman computation - they also wore vestments, so the domestic rituals of the synagogue religion of the era 70 to 2005 AD are somewhat artificial and synthetic, largely only obtaining in Judaism because the Temple was destroyed by the Roman Army in 70 AD. The origin then of the Christian vestment was sacred and religious, and not secular and political. From where did the reader get such a surprising opinion herself?
