This is very different. Roman Catholic Church was ordaining married men into priesthood until XII century (letting already ordained to look for women is another thing). General celibacy is disciplinary and not doctrinal.
Somebody please correct me if wrong, but does not the catholic church have a few married priests under a special dispensation because they came from another denomination into the catholic church?
It is also important to mention, that the Easter Orthodox priests who are married when they take their vows, can not rise in the ranks to bishop. Those remain unmarried postitions.
