Man, I started your post in such high hopes!
There are many things which we believe that are not defined one way or another by the Church.
Well, speaking for myself, in the area of faith I believe *nothing *which is not defined by the Church. If I could think of something, or if anybody challenges me on any statement of doctrine, I would compare the challenged opinion against our objective standard of belief, the Catechism. If my belief can be shown to contradict some part of the Content, then I am prepared beforehand to give up that unbelief.
I accept, with my mind, what is proposed for my belief by the Church. I embrace, with my will, what I accept with my mind. Thus,
I believe, I have the Faith.
I have no belief, in the area of my religion, outside of/other than the stated Content of Faith. Really!
I have, on the other hand, lots of opinions.
The examples you choose are not to me examples of beliefs.
Maybe I could see your point if you could illustrate it using an actual, undisputed belief of the Catholic Faith. Like,
Mary was Immaculately Conceived. Now, that is formally proposed for our belief, that we must believe to be Catholics, and that I do believe. If my belief in this proposition, unbeknownst to me, is in any way contrary to the way this truth is intended by the Church to be received by the faithful, then in advance I pray Mary and God to help my unbelief.
but, not!
Rather than “likewise”, the dissimilarity is stark between our Deposit of Faith, and what I have read on this thread so far as to the varying lists of beliefs for various non-denominational groups. Catholics, admire us or scorn us for it, have a Catechism stating the propositions we must accept as true (believe).
Can’t you use another word than “believe” when, in a Catholic context, you are outside the defined Deposit of the Faith? Such use of “believe”–the use which works in a sentence like (and I’m going for a clearly non-religious use), “I believe my shoe is untied,”–I submit that such use does not serve in conversation about religious belief.
What the individual members hold to be true, and what your Church B teaches them is true, may be two different things. They may be mistaken, due to ignorance or willfulness, as to the doctrine proposed for their belief by Church B. So what they think is “belief” is really “unbelief” in the teachings of Church B.
Because lots of Catholics think it’s OK to use contraception is irrelevant to whether or not the Catholic Church teaches us contraception is wrong. If people think it is right, they err, that’s all. They believe something which, insofar as they believe it,
makes them less Catholic. It is not a Catholic belief, and you can’t be Catholic and believe it. IN THAT RESPECT, one would be less-than-Catholic.
In fact, if you take it far enough, and public enough, and egregious enough, you will be self-excommunicated. You will truly
be not-Catholic.
