Jesus summoned his Twelve disciples and gave them authority over unclean spirits to drive them out and to cure every disease and every illness. The names of the Twelve Apostles are these: first, Simon called Peter, and his brother Andrew; James, the son of Zebedee, and his brother John; Philip and Bartholomew, Thomas and Matthew the tax collector; James, the son of Alphaeus, and Thaddeus; Simon the Cananean, and Judas Iscariot who betrayed Jesus. Jesus sent out these Twelve after instructing them thus,“Do not go into pagan territory or enter a Samaritan town. Go rather to the lost sheep of the house of Israel. As you go, make this proclamation: ‘The Kingdom of heaven is at hand.’” Matthew 10:1-7
We notice St. Peter is always listed first in every list of the apostles in the Gospels - Judas Iscariot is always listed last. This is one point showing the Primacy of Peter - he is higher than all of the other disciples. He was the first Pope! Peter's name is mentioned 155 times. All of the other eleven disciples combined are listed only 130 times.
We see in John 21:15-19, the discourse between Peter and Jesus. In this discourse, Jesus says, "Simon, son of John, do you love me more than these [the other disciples]?" Peter says "yes". In that conversation, Peter professes his faith in Christ three times to make up for the three times he denied our Lord during His Passion. Unlike Judas, who lost his soul because he refused to ask God's mercy for his actions, Peter is forgiven because he seeks forgiveness.
In the Acts of the Apostles, Peter is the spokesmen and always speaks for the group. People would lay in the streets just wanting Peter's shadow to fall on them (Acts 5:15). We clearly see that St. Peter was given a higher authority than the other disciples. My priest said he was the most worthy to be Pope. Why? Because Peter, before he knew Jesus, said, "Depart from me, Lord, for I am a sinful man" (Lk 5:8). Humility is the answer to following God. Through humility we are raised up and can hope to be perfect in Christ. For Jesus said, "You, therefore, must be perfect, as your heavenly Father is Perfect" (Matthew 5:48). This perfection is complete only through humility and St. Peter achieved it.
St. Peter was the first pope - the one that Christ founded His Church upon (Matthew 16:18-20).
