"I say unto thee, that thou art Peter, and upon this rock I will build my church; and the gates of hell shall not prevail against it." (Matthew 16:13-19)

St. Peter, for Catholics, has such important meaning because of his role in the history of salvation. When you read the New Testament, one will find that after the name of Jesus, the name of St. Peter is the one that appears the most. He is the one that Jesus chose to be the head of the Apostles and he told Peter to “confirm your brethren in the faith.” So Peter's role has been just that; to be the one who confirms us in our faith and maintains the unity of the Church.
