And as you know, Jimminy Cricket wrote that Jesus was particularly fond of shushi, but there are no extant copies of that either...So take it for what it's worth...
Matthew the tax-collector, for a Jewish Christian audience, he would have spoken the same language as Jesus, Aramaic.
Is the non extant Papias the same source that claims Jesus' language was Aramaic??? I suspect Jesus' language was any language he wanted to use at any given time...
Promoting the supposition that Matthew wrote the gospel in Hebrew but there is no documented proof is tantamount to a lack of faith in God’s ability to preserve His word “for all generations” as He promised.
