How? Your first sentence was "married priests are a theological impossibility."
That is simply not true. Marriage is perfectly compatible with the priesthood theologically, since there are, and have been throughout the Church's history, married priests.
Women priests are a theological impossibility. Married men being ordained to the priesthood are not.
And, a married priest's marriage in no way becomes "moot" at any time.
Last post on this thread to you, lest I am accused of "baiting" you.
Historical occurence of married priests is not a theological argument.
