Of course, binding and loosing have a larger function than what I addressed:
Mt.18.18-19 “Truly I tell you, whatever you bind on earth will be bound in heaven, and whatever you loose on earth will be loosed in heaven. 19 “Again, truly I tell you that if two of you on earth agree about anything they ask for, it will be done for them by my Father in heaven. 20 For where two or three gather in my name, there am I with them.”
I was referring to the specific “keys” given by Christ only to Peter. Go back and read my original post and see for yourself - #169.
Neither the binding and loosing function and power nor the use of the keys to the kingdom was unique to Peter's authority, nor flowed from him (as per Rome). The use of the keys to the kingdom was the gospel, which Peter first preached to the Jews, as providing for forgiveness and regeneration by faith in the crucified and risen righteous Lord Jesus, was exercised by Peter before he was given the revelation of Acts 10 (which Paul received independent of Peter).
