Are you kidding? What do you think he meant to do with his comments to the Nigerian Bishops?
He would like them to shut up and stop whining but he is far too polite to put it quite that directly.
As to Middle Ages married priests: has it occurred to you that various sins have been practiced, often by large populations, for long durations, despite the existence of the 10 Commandments since about, say, 5000 BC?
The fact that people ignore Commandments and/or disciplines does NOT mean that the Commandment or discipline did not exist.
Perhaps at another seminary you would have learned logic 101, as well as analogy.
Perhaps you could re-read what I wrote. Comparing optional celibacy to the 10 Commandments (which are not optional) is the height of illogic.
Declaring something settled in a matter of faith is wholly different from declaring a discipline settled. Catholics will continue to discuss optional celibacy whatever the Pope says.
JP II strongly urges the end of capital punishment. Should we shut up about that one too, even though the Church recognized the validity of the practice for 2000 years?
