You may want to do some research on what binding and loosing really is, you be astounded at what you will find.
It means giving authority to the Apostles and Peter.
Acts 5:13 - the people acknowledged the apostles’ special authority and did not dare take it upon themselves.
Acts 15:6,24; 16:4 - the teaching authority is granted to the apostles and their successors. This teaching authority must be traced to the original apostles, or the authority is not sanctioned by Christ.
Rom. 15:16 – Paul says he is a minister of Christ Jesus to the Gentiles in the priestly service of the gospel of God, so that the offering of the Gentiles may be acceptable. This refers to the ministerial priesthood of the ordained which is distinguishable from the universal priesthood of the laity. Notice the Gentiles are the “sacrifice” and Paul does the “offering.”
1 Cor. 5:3-5; 16:22; 1 Tim. 1:20; Gal 1:8; Matt 18:17 – these verses show the authority of the elders to excommunicate / anathemize (“deliver to satan”).
2 Cor. 2:17 - Paul says the elders are not just random peddlers of God’s word. They are actually commissioned by God. It is not self-appointed authority.
2 Cor. 3:6 – Paul says that certain men have been qualified by God to be ministers of a New Covenant. This refers to the ministerial priesthood of Christ handed down the ages through sacramental ordination.
2 Cor. 5:20 - Paul says we are “ambassadors” for Christ. This means that the apostles and their successors share an actual participation in Christ’s mission, which includes healing, forgiving sins, and confecting the sacraments.
2 Cor. 10:6 – in reference to the ordained, Paul says that they are ready to punish every disobedience. The Church has the authority excommunicate those who disobey her.
2 Cor. 10:8 - Paul acknowledges his authority over God’s people which the Lord gave to build up the Church.
1 Thess. 5:12-13 - Paul charges the members of the Church to respect those who have authority over them.
2 Thess. 3:14 - Paul says if a person does not obey what he has provided in his letter, have nothing to do with him.
1 Tim. 5:17 - Paul charges the members of the Church to honor the appointed elders (“priests”) of the Church.
Titus 2:15 - Paul charges Timothy to exhort and reprove with all authority, which he received by the laying on of hands.
Heb. 12:9 – in the context of spiritual discipline, the author says we have had earthly fathers (referring to the ordained leaders) to discipline us and we respected them.
Heb. 13:7,17 - Paul charges the members of the Church to remember and obey their leaders who have authority over their souls.
1 Peter 2:18 - Peter charges the servants to be submissive to their masters whether kind and gentle or overbearing.
1 Peter 5:5; Jude 8 - Peter and Jude charge the members of the Church to be subject to their elders.
2 Peter 2:10 - Peter warns the faithful about despising authority. He is referring to the apostolic authority granted to them by Christ.
3 John 9 - John points out that Diotrephes does not acknowledge John’s apostolic authority and declares that this is evil.
Deut. 17:10-13 - the Lord commands His faithful Israel to obey the priests that He puts in charge, and do to all that they direct and instruct. The Lord warns that those who do not obey His priests shall die.
Num. 16:1-35 - Korah incited a “protestant” rebellion against God’s chosen Moses in an effort to confuse the distinction between the ministerial and universal offices of priesthood, and Korah and his followers perished. (This effort to blind the distinctions between the priests and the laity is still pursued by dissidents today.)
Sirach 7:29-30 - with all your soul fear the Lord and honor His priests, love your Maker and do not forsake His ministers. God is not threatened by the authority He gives His children! God, as our Loving Father, invites us to participate in His plan of salvation with His Son Jesus. Without authority in the Church, there is error, chaos and confusion.
