How many popes are there suppose to be according to the bible?

Answer 1

NONE.

Jesus Christ is his own vicar. His name alone is Reverend (Psalm 111.9), and he is the only father;-

And call no man your father upon the earth: for one is your Father, which is in heaven. (Matthew 23.9)

Answer 2

Jesus Christ appointed Peter as the first leader of his Church when He said:

And Jesus answering, said to him: Blessed art thou, Simon Bar-Jona: because flesh and blood hath not revealed it to thee, but my Father who is in heaven. And I say to thee: That thou art Peter; and upon this rock I will build my church, and the gates of hell shall not prevail against it. And I will give to thee the keys of the kingdom of heaven. And whatsoever thou shalt bind upon earth, it shall be bound also in heaven: and whatsoever thou shalt loose upon earth, it shall be loosed also in heaven. (Matthew Chapt. 16)

Peter is considered the first pope even though the term 'pope' did not come into common usage until much later. Whether Peter was in Jerusalem, Antioch, Rome or elsewhere, he is still considered the first pope. Later, as the Church grew and a hierarchy developed. the Church established its headquarters in Rome as Rome was considered the center of the world at the time.

Since only Peter was chosen as the first leader of the Church and not several of the apostles, we must assume that he intended the Church to have only one leader at a time.

Answer 3

None. The Bible was written before there were any popes.
