[George J. Jetso]

I thought the pope did not make a mistake so why do the want to go back to priests getting married?

[GingisK]

To keep them from porking the choir boys.

[Cronos]

Papal infallibility is the Holy spirit preventing the pope from making dogma errors when he pronounces a dogma ex cathedral.

It does not mean he cannot and does not make errors about policy, politics or which football team will win.

And in this case it is a discipline not even a dogma.

There are 23 rites in the Catholic church. You probably only know of the Latin rite. All the other rites allow married men to become priests.

So you have married men who are Maronite Catholic priests, who are Syro Malabar, Malankara, Byzantine Catholic etc priests.
