I agree but some would say that because Scripture is “God breathed” and hence infallible, (it should be inerrant) it is the only reliable Authority.
If Scripture alone is the only reliable authority, then why is it those who make Scripture alone their authority are unable to agree on what Scripture teaches?
For example, some believe that Scripture teaches that Baptism provides grace, and some believe it is only symbolic act proclaiming one’s membership. Some believe Scripture teaches us that one should Baptise in the name of the Father, Son and Holy Ghost, and others believe it teaches we should baptize in the name of Jesus.
Some believe that Scripture shows that the Eucharist provides grace, and others believe it teaches it is only a memorial supper. Some believe Scripture teaches we do not need any kind of sacraments whatsoever.
Some believe that Scripture teaches Once Saved always Saved, and others believe the Scriptures teach the opposite.
Some believe that Scripture teaches that salvation is a matter of freewill, and others believe it teaches we are predestined to heaven or hell.
Jesus gave the Church authority to teach because without it, everyone becomes his own Pope and decides what is right, and the result is chaos (which is what you have with Protestantism continuingly fragmented, which NOT what Jesus intended for his church).

I am asking if this presuppostion is found anywhere in Church history prior to the Protestant Reformation.
Probably the best place to look is the early Church Fathers. But from reading Orthodox and Catholic writers, I’ve gotten the impression that both Catholic and Orthodoxy were united in beliefs (despite some differences of opinion) and that Sola Scriptura was unknown until Luther’s revolt.
