[quote=Sir Knight]I quoted Matthew 16:19 - I will give you the keys of the kingdom of heaven, and whatever you bind on earth shall be bound in heaven, and whatever you loose on earth shall be loosed in heaven." as one of the bases for the Catholic Church’s authority and was told the following …
Notice the words “shall” in each phrase. Shall is future. It could easily read like this: “Whatever you declare to be sin on earth will then be bound in heaven, etc.”
If Jesus were giving Peter a commandment to only teach things that were already true in Heaven (which, by the very nature of the Church, it does!!), the sentence structure would be reversed. Jesus would’ve said: Whatever is bound in heaven shall be bound on earth, etc.
Also, the context of the sentence points to the Catholic interpretation: Jesus is giving the “keys” or the authority to Peter. By telling Peter that whatever he binds on earth shall be bound in heaven, Jesus is showing just how much authority He has given Peter and the Church Militant.
Furthermore, Jesus tells His apostles that “As the Father sends Me, so I send you.” Whoa! Talk about authority! Jesus says that He is sending the apostles with in the same way that the Father sent Jesus. What did Jesus have authority on earth to do? Forgive sins, bind sins, turn bread and wine into His body and blood, heal the sick, perform exorcisms, ordain followers (apostles), seal people with the Holy Spirit, baptize . . .
