The word “Pope” is Latin for “Father”. The Bible speaks of God as “Our Father”,
Matthew 6:99 After this manner therefore pray ye: Our Father which art in heaven, Hallowed be thy name.
Scripture also says that the Apostles considered themselves the Fathers of their flocks:
1 Corinthians 4:15
15 For though ye have ten thousand instructers in Christ, yet have ye not many fathers: for in Christ Jesus I have begotten you through the gospel.
1 John 2:1My little children, these things write I unto you, that ye sin not. And if any man sin, we have an advocate with the Father, Jesus Christ the righteous:
Because Jesus Christ appointed Simon to “feed” His flock. The Church has always called him the first “Pope” or “Father” of the Church:
John 21:1717 He saith unto him the third time, Simon, son of Jonas, lovest thou me? Peter was grieved because he said unto him the third time, Lovest thou me? And he said unto him, Lord, thou knowest all things; thou knowest that I love thee. Jesus saith unto him, Feed my sheep.
