The Holy Apostle Peter, the son of Jonah and brother of Andrew the First-Called, of the tribe of Simeon and the town of Bethsaida, he was a fisherman and was at first called Simon, but the Lord was pleased to call him Cephas, or Peter (Jn 1:42). He was the first of the disciples to give clear expression to his faith in the Lord Jesus, saying: "Thou art the Christ, the Son of the living God" (Mt. 16:16). His love for the Lord was very strong, and his faith in Him went from strength to strength. When the Lord was put on trial, Peter denied Him three times, but it needed only one look into the face of the Lord, and Peter's soul was filled with shame and repentance. After the descent of the Holy Spirit, Peter became a fearless and powerful preacher of the Gospel. After his first sermon in Jerusalem, about 3,000 souls were converted to the Faith.
