——God has that authority.——
And He gave authority to His Church, if you believe Him.

“If your brother sins [against you], go and tell him his fault between you and him alone. If he listens to you, you have won over your brother.
If he does not listen, take one or two others along with you, so that ‘every fact may be established on the testimony of two or three witnesses.’
If he refuses to listen to them, tell the church. If he refuses to listen even to the church, then treat him as you would a Gentile or a tax collector.
Amen, I say to you, whatever you bind on earth shall be bound in heaven, and whatever you loose on earth shall be loosed in heaven.

The only debatable question is whether the Catholic Church is the visible (you can’t take disputes to an invisible church), authoritative Church that He established, which the gates of hell would not prevail against.
The answer to this question is a matter of historical analysis. There is only one Candidate. As Cardinal Newman said, to be deep in history is to cease to be Protestant.
Analysis, to be accurate, must be unbiased. The Catholic Church does indeed have some history behind it. The list of grievances is long. Enough to fill books. There probably are books on this very subject but I do not seek them out. The Catholic Church does not meet the criteria to be Gods authoritative church. Teaching the traditions of man instead of the commandments of God is just one.
