a reference on the priest MUST be husband of one wife
As far as the "one" count, as far as I know, we only have one reference in
new testament, but it's from the synogogue's star pupil of torah:
1 Tim 3:2
"A bishop then must be blameless, the husband of one wife, vigilant, sober, of good behaviour, given to hospitality, apt to teach"
We make a lot of errors reading the bible as if it were written in english and with modern expression of point. In greek, "must" doesn't mean "if / then / must." Some also read that as "preacher" or "deacon."
He wasn't creating "bishop", he was fresh out of the synagogue and meeting Y'Shua, the high Priest.
And while torah doesn't say "only one", leviticus reiterates the "must" with the usage of "shall" which also presents an idea of imminence.
Leviticus 21:13
"And he shall take a wife in her virginity."
Also somewhere in Ezekiel
That's about as good as I can do, it seems also like one of the OT source texts may say "one virgin", but don't take that unless you find it for yourself, because
I might be remembering wrong.
What would He have said to others to explain not getting physically married? Probably something mysterious
like "Don't you know I must be about my Father's work?"
Or maybe
like "Don't you know that a priest must only have one wife?" -not trying to put words in His mouth, just imagining the man like the rest of us.
I just can't mentally make Him having a physical wife a part of the story. I even think He could have married Mary M. if He had wanted to, maybe even considered it, but if He loved her that way, I think He would rather have spared her becoming a widow.
