Compare Matthew 16 with 18 regarding binding and you'll see that the keys are not unique to Peter, all Christians have them.

I am Catholic. I am familiar with the Holy Scripture. Why don't you do the comparing and tell me if you see any keys to the Kingdom of Heaven in Matthew 18, or if there is anyone beside St. Peter promised them.

What do keys do? The same thing in both places. We Christians can all bind and loose therefore we all have the same keys.
