I'm an ordained minister (are you?) whose studies are ongoing, but that's frankly irrelevant. Only what the Bible says matters, and the Bible is quite clear on these issues--if it were not, you would have countered me from the Scriptures rather than trying to hide behind a wordy and less-authoritative ecumenical council.
And that is EXACTLY your problem. The Ecumenical Councils hold the same authority as scripture. I would be willing to bet you are 7th Day Adventist or some other similar group. Talk about no credibility. My Church, the one and only original (accept NO substitutes) has been here from the BEGINNING!
