So you're saying that anything anybody did or said after 100 AD is not, in any way, inspired or authoritative. I will have to disagree completely with you on that. I'm sure you are making the same old argument that - if it's not in the Bible, then it's not true or valid.
But that just takes us back to your original argument.
My argument is simple - if something cannot be demonstrated to be a legitimate Christian belief during the first 100 years of the church, it didn’t originate from the Apostles or the Scriptures. It is an accretion of history and probably pagan in origin. As such, it is a false belief and not Christian.
I’m fine with disagreement... I’m just pointing out that beliefs as discussed on this thread, do not find their origin in the inspiration of the Holy Spirit, as recorded in Sccripture, nor any identified Apostolic Tradion in the original Church.
For most of these pagan customs, you must go out hundreds of years before they find entry into the church.
