Don’t want to get too much in the weeds over terms such as discipline and dogma and doctrine.
Suffice it to say, I think many Catholics including myself always thought that the compulsory clerical celibacy policy was something that was always in place and was basically etched in stone.
After doing quite a bit of research, I learned quite to the contrary.
I too used to think it was etched in stone and was always like that until researching it. Chalk it up to poor catechesis I guess.
With that said though, it’s not going away. In theory it could, but the likelihood is exceedingly remote.
