So now you are saying that the Gospels of Matthew and Luke, both written in Koine Greek, both using the word Epiousios ( επιούσιος ) in the Lord's Prayer are errant?
I want to go on record here that the Gospels were written in Hebrew, and later translated to Greek and Aram. The Hebrew and Aram MS were largely destroyed in great numbers when Rome sacked Israel, which is the primary reason for the dominance of Greek MS.
There are many corrupted Greek MS in this world, and I can see why you’d love them.
