Was Paul talking in types and federal heads or teaching biology with the reference to Adam? Biology say the literalists. The jump from literal history to spiritual needs clarification. Of course old earth creationists need extra fixes. They think Adam is literally and historically the first man of this creation. The Bible inconveniently doesn’t mention these creations, nor does the geological record. They believe there were men before Adam in these other creations. So Adam is the first one this time. Complicated for first and fundamental principles hey?
