People are scared of St. Peter and rightfully so. Because the truth is that he killed two people with his power. It's in Acts. He killed a husband and wife. The man dropped dead of fright but St. Peter actually spoke a curse to the wife and then she fell down dead. So the real reason why people fear St. Peter, and why so many workers will not teach you to work with him, is that he can and will kill people. So it's not just about opening and closing some one's way, but also he has the power to take lives. That is a power granted to him by God. And you know what I find so funny? Most Fundamentalist Christians can read this passage below and simply will not recognize it as being a curse that St. Peter did. They literally have no clue.
Acts 5:1-11 KJV
1But a certain man named Ananias, with Sapphira his wife, sold a possession,
2And kept back part of the price, his wife also being privy to it, and brought a certain part, and laid it at the apostles' feet.
3But Peter said, Ananias, why hath Satan filled thine heart to lie to the Holy Ghost, and to keep back part of the price of the land?
4Whiles it remained, was it not thine own? and after it was sold, was it not in thine own power? why hast thou conceived this thing in thine heart? thou hast not lied unto men, but unto God.
5And Ananias hearing these words fell down, and gave up the ghost: and great fear came on all them that heard these things.
6And the young men arose, wound him up, and carried him out, and buried him.
7And it was about the space of three hours after, when his wife, not knowing what was done, came in.
8And Peter answered unto her, Tell me whether ye sold the land for so much? And she said, Yea, for so much.
9Then Peter said unto her, How is it that ye have agreed together to tempt the Spirit of the Lord? behold, the feet of them which have buried thy husband are at the door, and shall carry thee out.
10Then fell she down straightway at his feet, and yielded up the ghost: and the young men came in, and found her dead, and, carrying her forth, buried her by her husband.
11And great fear came upon all the church, and upon as many as heard these things.
