I think most do understand the to be married, as to “get married” after they become a priest. Yes, there are those very rare few that are married, were married, then subsequently (later) become Catholic priests, or perhaps some that had a wife predecease them before they became a priest. I’ve not come across any personally. The Catholic priests and nuns still take a vow of celebacy the last time I checked, but maybe that has been dropped. I’m old school learned, but new age and trying to keep up with it all.
