There are married Roman Catholic priests in the Eastern Rite churches.
The real question is, why is there a double standard for Roman Catholic priests?
You wrote: "There are married Roman Catholic priests in the Eastern Rite churches."
Incorrect. There are married priests in the Eastern Catholic churches. There are no married "Roman Catholic" priests in the Eastern rite churches.
"The real question is, why is there a double standard for Roman Catholic priests?"
There is no doublestandard. The same thing is expected from every man who comes to the priesthood in the Roman Church as a single man.
Which was my point all along.
