I dealt with Thess first, so it made sense then to go backward to the Lord's words. :>)
In any case, which traditions are we to keep and which are we not to keep.
BTW, show me a verse in which the Apostle Paul supports icon veneration/worship. You're going to really surprise me if you can.
There isn't a verse because the epistles St Paul wrote were not 'the written version of everything I've told you to do and not to do'. They were written to correct incorrect practices.
Archaological evidence proves that Christians venerated icons in the Early church.
That St Paul does not have an epistle correcting that bheavior is strong evidence of his support for it.
