It makes no sense to you because you don't know what a pope is.It is interesting to note that while Peter is prominent in the first 12 books of Acts, the apolstle Paul is the prominent figure in chapters 13-28. This makes no sense if Peter had become pope.
I'll help. Imagine sitting in a your community building listening to one of the preachers you think is agreat. You would say that the Holy Spirit is guiding him in his preaching. We think the same about the pope.
