No, it’s
not an opinion. Opinions don’t have objective truth values. Opinions are statements like, “Those shoes are pretty,” or “Oranges are better than apples.” Those statements don’t have objective truth values.
The statement, “If they were following all of Christ’s teachings, they’d be Catholic,” has an objective truth value. It is either true for everyone or it is false for everyone. Therefore it cannot be a statement of opinion.
No, it’s our
belief that that’s the case. Since we are affirming a statement with an objective truth value, it is not our opinion, but our belief.
He doesn’t share that
belief, to be sure
God judges what facts are true and what facts are false, regardless of our beliefs, but false (or possibly false) beliefs do not suddenly become opinions.
