How was Saint Peter a normal and ordinary person?

Answer 1

Peter was a simple fisherman from a low middle class family of hard working Jews. He was, at times, impulsive - saying the wrong thing at the wrong time. More than once Our Lord called him on this. Peter had little education. He could be weak willed and not loyal, even denying Our Lord three times. He lacked leadership skills at times when the other apostles sought him out for advice. He was not much different from most humans. However, things changed in a big way after Pentecost.

Answer 2

According to Acts of the Apostles, Peter could perform the same miracles as Jesus had done, even raising Tabitha from the dead. On this account, Peter was far from a normal or ordinary person. One view of Acts would be that it is an extreme form of hagiography in the way it portrays Peter as being able to perform miracles at will. New Testament scholars say that Acts of the Apostles is a book of miracles rather than of history. Uta Ranke-Heinemann (Putting Away Childish Things) goes as far as to say that the whole of Acts is a simply a work of Propaganda. If Saint Peter did not perform any miracles at all, this brings him back to the ranks of ordinary people.
