As the only other statement provided is my own request, the conclusion does not follow.
You are mistaking a reason for believing a statement for a conclusion following from that premise. The reason we should be Catholic is because Catholicism is true. "Because" is not the same as "therefore". If someone had claimed: "We should be Catholic. Therefore Catholicism is true.", that would be a non sequitur. But if someone claims "We should be Catholic because Catholicism is true.", that is *not* a non sequitur. That conclusion [we should be Catholic] *does* follow from the premise [Catholicism is true]. And that is because we should believe whatever is true.

And you are caviling.
I have no time for pettifogging.
Consider this my concession, and your "win."
