Well no, scriptures certainly are not ALL catholic as these threads do attest to. But of course it is quite understandable a catholic such as yourself might see it as so.
On "these threads" (which and where?) I see plenty of questions about the Catholic faith in general and asking for Catholic explanations of certain passages. I also see the explanation then causing further questions, some stemming form lack of understanding, others from curiosity, yet others from a desire not to leave the field after the game is over. I do not see any instance where a biblical passage would be posed to me and I would not be able to give a Catholic explanation, other than, of course where a miracle not subject to laws of nature is discussed. If there is such an instance, please point it to me by thread and post number. You will do me a favor by also reviewing for yourself the answer I gave to that post before we go into circular posts.
