What you bind on Eaarth will be bound in Heaven, what you loose on Earth shall be loosed in Heaven.....given that promise, do you really think that God would allow the church to make an error???....Nope, He promised that He would protect her from that and so far He is doing just fine.
We could also point to the worship of Mary by cathicism.
That raises more questions:
Do you believe the popes and councils have never erred or contradicted themselves in what they wrote and required RCs to do? So that you are bound to obey all such?
Or is this restricted to a minority of teachings, and so you may disagree with those that are not as they may be in error?
Do you have an infallible list that tells you all the infallible teachings? Or is this subject to interpretation?
Is the CCC infallible so that it never may be in error or contradict itself? Is it or other RC teachings subject to interpretation by those Rome holds as members, without discipline?
And since the power to bind and to loose was also given to the OT magisterium, with disobedience resulting in death, (Dt. 17:8-13) and in Mt. 18:15-20 applies to judicial actions in personal disputes, and beyond that spiritually applies to all believers, then why do you think this is unique to the Roman magisterium, and means it cannot err?
Since the basis for your assurance of Truth - that Rome cannot err - is what Scripture says, then how are you different from an evangelical whose basis for assurance of Truth is the weight of Scriptural substantiation?
Is your RC argument is that an assuredly (if conditionally) infallible magisterium is essential for determination and assurance of Truth (including writings and men being of God) and to fulfill promises of Divine presence, providence of Truth, and preservation of faith, and authority. (Jn. 14:16,26; 15:26; 16:13; Mt. 16:18; Lk. 10:16)
And that being the historical instruments and stewards of Divine revelation (oral and written) means that Rome is that assuredly infallible magisterium. Thus any who knowingly dissent from the latter must be in rebellion to God?
Thanks for helping us to better understand RC reasoning.
