Indeed, I have spent a great deal of time with my brother speaking of Christ. He does not demean my point of view, nor do I demean his - nor do either of us demean the view of other Christians.
We are both Christian, our witness is just a bit different - which is o.k. according to Scripture. Thanks for mentioning Apollos, the difference between Apollos and Paul is a good example:
For while one saith, I am of Paul; and another, I [am] of Apollos; are ye not carnal? Who then is Paul, and who [is] Apollos, but ministers by whom ye believed, even as the Lord gave to every man? - I Corinthians 3
Perhaps if we could spend more time rejoicing our similarities, instead of fuming about our differences, we could persuade others to consider the Lord. Personally, I don't believe it matters one whit to God when or under what circumstances we believe the first ensouled man was created. That is not His point. The whole focus of the Bible is to demonstrate that ALL of us fall short, but that God desires above all else to be reunited with His creation...so much so, that He sent us Christ because none of us can ever be perfect. Perfection can and will only be attained by reunification with Him.
Until then, as I suggested before, let us rejoice in our similarities and ultimate destination.
