While I was writing what was to be my final post on this thread, you wrote, "I'm not sure where in the New Testament Genesis is specifically affirmed..." I had already posted before I read your (implied) question to guest, Pete. I see he hasn't answered yet (though no doubt he could), so I will answer.
Here are a few places in the NT which affirm the earliest chapters of Genesis:
Matthew 19:4-6 - He* answered, "Have you not read that he who created them from the beginning made them male and female**, 5and said, 'Therefore a man shall leave his father and his mother and hold fast to his wife, and the two shall become one flesh'***? 6So they are no longer two but one flesh. What therefore God has joined together, let not man separate."
** *Genesis @:24
Acts 17:24-28 - The God who made the world and everything in it, being Lord of heaven and earth, does not live in temples made by man, 25nor is he served by human hands, as though he needed anything, since he himself gives to all mankind life and breath and everything. 26And he made from one man every nation of mankind to live on all the face of the earth, having determined allotted periods and the boundaries of their dwelling place, 27 that they should seek God, in the hope that they might feel their way toward him and find him. Yet he is actually not far from each one of us, 28for
"'In him we live and move and have our being';
as even some of your own poets have said,
"'For we are indeed his offspring.'
See also Luke 3:38, John 1:1-3, Acts 14:15-17, Romans 5:12,14; I Corinthians 15:22,45; I Timothy 2:13,14, Jude 14, among others.
I hope you find this helpful. Thank you again (and thank you all) for an interesting and informative discussion. Good night.
