[quote=Angainor]I have heard it said by Catholics that when Jesus was speaking to John on the cross he really didn’t mean just John at all, but everyone, when he said:…he said to his mother, "Dear woman, here is your son,"and to the disciple, “Here is your mother.” John 19:26-27
This is used to support the idea that Mary is the mother of us all (or something).
However, when Jesus gives the keys of the kingdom to the Rock, that absolutely cannot be interpreted to mean anyone other than Peter himself. In other words, Jesus was not giving the keys to any faithful servant, but to the specific faithful servant to whom he was speaking.
Catholics emphatically say we musn’t expand Jesus’ words to mean more than Peter, at the same time they are expanding Jesus’ words to mean more than John.
Why are the two instances treated so differently?
The truth is the exact opposite interpretations should apply - here’s why we know that for sure.
When Jesus gave the keys to Peter in Matthew 16:19, he says "
“I will give you the keys of the kingdom of heaven; and whatever you bind on earth shall have been bound in heaven, and whatever you loose on earth shall have been loosed in heaven.”
Jesus then extends those same keys to ALL of the disciples when in chapter 18 he says, “Truly I say to you, whatever you bind on earth shall have been bound in heaven; and whatever you loose on earth shall have been loosed in heaven.”
Another major confirmation that Peter isn’t the only one the church is built upon comes from Ephesians 2:20 when Paul says, “So then you are no longer strangers and aliens, but you are fellow citizens with the saints, and are of God’s household, having been built on the foundation of the apostles and prophets, Christ Jesus Himself being the corner stone, in whom the whole building, being fitted together, is growing into a holy temple in the Lord, in whom you also are being built together into a dwelling of God in the Spirit.” Note that the foundation is ALL of the apostles and prophets, not just Peter. The only individual singled out for special recognition is the chief cornerstone, which is Jesus, as he should be.
No other proof is needed to know that Peter, while first among equals, is not the sole rock upon which the church is built. He was simply the first among those who were recognized. ALL of the apostles AND prophets share equal weight as the foundation of the Church. Scripture can’t be more clear on this.
As for John representing the Church, that’s not consistent with what actually followed. Jesus was doing a very practical thing. His love for his mother led him to place her into his beloved disciples care for the remainder of her life. Tradition holds that John took her in and cared for her 'til her death.
