"For two people with such differing points of view, it is useless to argue unless we come together on the subject of Authority, which we will probably never do."
Certainly I agree with you on this point. All disputed questions of Faith finally come down to which authority one accepts.
It took ARCIC (the Anglican Roman Catholic International Commission) 30 years to come to this conclusion - I'm pleased to see that your wits are somewhat sharper!
But on what do you base your authority and why? What is your pillar and ground of the truth?
I Tim 3:16-17. Summary: States the bible is sufficient for everything you need, makes one complete, no mention of oral tradition. Catholics contend scripture here means only the OT, but Peter mentions that Paul's writings are scripture.
