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?
Who said anything about doctrine or dogma? Are you confused? Celibacy is a discipline, but OBEDIENCE is a Commandment. Yes, there is a moral issue involved.
Surprised I had to point that out for you.
As to cap punishment: I used to be a hardliner on the issue--'hang em high.' Then I asked myself: could I actually pull the switch for the electric chair?
The Pope's statement concerned affluent countries, and was by no means unconditional.
Are you confused? Do you not understand the difference between exhortation and command?
