Matrimony ---> then ---> Holy Orders (priest): yes (sometimes)
Holy Orders (priest) ---> then ---> Matrimony: no (never)
In the same way, in the Catholic Churh there are married men who have become priests (usually in one of the non-Latin Churches, or possibly priest-converts from Anglicanism) --- but nobody who is a priest, first, can THEN get married and continue to serve as a priest.
It has always been in this way, in the Catholic and Orthodox churches, going back to the time of the Apostles.
Well said, Mrs. D.
