I can’t answer your question unless I know what you mean by *Catholic* and what you mean by *Christian*.
It’s intellectually dishonest to demand an answer to a question and expect me to provide the definitions of the words you are using. If you want a clear, precise answer, you must be clear and precise about the meanings of the terms you are using.
Since you are asking the question, it is up to you to provide the definitions.
Ah, but those are precisely the definitions that I seek from you!
