Question: Jesus said, "I will give unto you the keys of the kingdom of heaven: and whatsoever you shall bind on earth shall be bound in heaven...if two of you shall agree on anything it shall be give you...." Why can't we make this work today?

Response: The Catholic Church teaches that the "keys" were only for Peter (and his "successors," the popes) and the the "binding and loosing" authority was for all of the apostles (including Peter) and their "successors," the bishops, et al. Clearly the "keys" in Matthew 16 are connected with the "binding and loosing," an authority given to all of the disciples in Matthew 18. Obviously, the gospel and sound doctrine are the "keys" to the Kingdom. Peter used these keys to unlock the Kindom to the Jews through his sermon on the Day of Pentecost in Acts 2; and in Acts:15:7And when there had been much disputing, Peter rose up, and said unto them, Men and brethren, ye know how that a good while ago God made choice among us, that the Gentiles by my mouth should hear the word of the gospel, and believe.
See All... Peter seems to indicate that he used these keys again when he preached the gospel to the Gentiles in Cornelius' house in Acts 10. Every Christian is a successor to the apostles, and we have the same authority they had to bind and loose. What does it mean?

The "binding and loosing": in Matthew 16 is further illustrative of "keys." Keys are used both to lock (bind) and unlock (loose). The gospel of Jesus Christ which we preach sets free from sin (looses) those who receive it and condemns (binds) those who reject it. Furthermore, in Matthew 18 "binding and loosing" is linked with the promise, "Where two or three are gathered together in my name, there am I in the midst of them." That promise applies not to some special "prophet" or "official church hierarchy," but to all Christians. The context and the entire tenor of Scripture make it clear that Jesus is not handing His disciples a magic power to wield as they please. He is telling them that as His representatives they are to act in His name. This is no different from His promise that "Whatsoever ye shall ask the Father in my name, he will give it you" (Jn:16:23And in that day ye shall ask me nothing. Verily, verily, I say unto you, Whatsoever ye shall ask the Father in my name, he will give it you.
See All...). Invoking His name in prayer is not a magic formula whereby we receive automatic answers to our requests. His name must be stamped on our character and engraved on our hearts, not just on our lips. To ask in His name means to ask according to His will and to His glory. The same is true with "binding and loosing"—it must be in His name and through His Word.
