Right. The pre-Vatican II Church was vigilant against homosexuals, yet many became priests because they learned the rules and stayed within the rules.
This new declaration will remove the open homosexual practices in seminaries. That certainly needs to be done, if it hasn't been done already.
But gays have snuck into the military, and they'll sneak into the priesthood.
If they're celibate, there will no problems, as has been the case for a thousand years.
