Neh. The Church imposed rule of celibacy of the priesthood is first and foremost, a doctrine. No one who has not been indoctrinated in the Faith would know this otherwise.
I’m not denying that it’s a discipline. But merely pointing out that no one who wasn’t taught, no one who wasn’t indoctrinated, would know this to be true.
The fallacy of equivocation occurs when a key term or phrase in an argument is used in an ambiguous way, with one meaning in one portion of the argument and then another meaning in another portion of the argument.
I’m using the word “doctrine” consistently to mean teaching.
Here’s the problem. Lazy, imprecise use of language.
If someone says, Sola Scriptura is not a doctrine, because its a hermeneutical principle. Catholics will immediately recognize the error in such a statement. Because the two terms, hermeneutical principle and doctrine, are not mutually exclusive.
People have to be taught to use Scripture as a hermeneutical principle. People have to be indoctrinated to use Scripture as a hermeneutical principle. That makes it a doctrine.
It’s the same thing with disciplines in the Catholic Church. People have to be indoctrinated as to what are disciplines in the Catholic Church.
If a person says, “a discipline is not a doctrine.” What he actually means to say is, “a discipline is not an ABSOLUTE doctrine given to us in the Deposit of Faith.”
Here’s the way I understand Catholic Doctrine.
Catholic Doctrine is the whole.
There are three types of that.
I. Doctrine which is the equivalent of Tradition with a Capital T. I normally capitalize the D to show that it is absolute doctrine that can’t be changed. It comes from the deposit of faith.
Within this set, there is:
A. Dogma is the type of Doctrine that is extraordinarily defined and unchanging.
B. Doctrine which is not extraordinarily defined. But infallible nonetheless.
- These include Sacraments, some Canon Law, some Rules of the Church (i.e. Sunday day of obligation).
II. Then, there’s doctrine which is the equivalent of tradition with a small t. It can change and does when the Church judges they need to be changed. Within this category of Catholic Doctrine, fall the:
A. liturgies, laws, disciplines and rules of the Church,
B. practices, prayers, some histories which are highly valued but can’t be verified.
