Matthew 16:19
I will give you the keys of the kingdom of heaven; whatever you bind on earth will be bound in heaven, and whatever you loose on earth will be loosed in heaven.”
1 Timothy 3:15
"...which is the church of the living God, the pillar and foundation of the truth."
Matthew 18
15“If your brother or sisterb sins,c go and point out their fault, just between the two of you. If they listen to you, you have won them over.
16But if they will not listen, take one or two others along, so that ‘every matter may be established by the testimony of two or three witnesses.’d
17If they still refuse to listen, tell it to the church; and if they refuse to listen even to the church, treat them as you would a pagan or a tax collector.
18“Truly I tell you, whatever you bind on earth will bee bound in heaven, and whatever you loose on earth will bef loosed in heaven.
Bishop St. Cyprian the Martyr of Carthage in 252 [Epistle 59:14 in PL ],
After such things as these, moreover, they still dare--a false bishop having been appointed for them by, heretics--to set sail and to bear letters from schismatic and profane persons to the throne of Peter, and to the chief church whence priestly unity takes its source; and not to consider that these were the Romans whose faith was praised in the preaching of the Apostle, to whom faithlessness could have no access.
Perhaps you might read the Old Testament and find the same proofs were claimed as promised the same way by the religious authorities of Judaism. They were wrong then... What makes you think you’re interpreting those promises rightly now?
The Muratorian fragment represents the canon of scripture for Rome, c. 180 A.D. It contained the NT, but has some missing pieces. It also had the Revelation of Peter, a Gnostic text.
An infallible church in Rome has a Gnostics text right under their own nose within their canon of inspired scripture.
Yeah, the church in Rome sure was infallible all right...
