“Can you show me that he affirmed the exact dating of Genesis, that exactly, how ever many years prior to His existence on earth, Noah sailed in the Ark?”
Taking the details of the Genesis account literally does not require an exact date or chronology.
The issue here is literal versus figurative.
I take the events as actually happened. I do believe in the creation of man. I do believe in the Flood. I do believe that everything Genesis teaches did happen.
I just quibble with Fundamentalists who think they can give me a date as to when it happened, yet the historical evidence for some of these happenings don’t jell with the Fundamentalist point of view.
Especially pre-flood dating.
