Where did Jesus teach bible alone? Where did He teach that the faith - the Christian faith - would involve anything written whatsoever? Where did He teach that we are to run to the bible and argue over doctrinal matters?
He did not. Never.
Read Luke 10:16 "He who HEARS you HEARS Me.
Read the didache, the earliest known catechism. Written while the Apostle John was yet living. It delineates all sorts of things about the faith, but not a peep about anything written.
Jesus sent Apostles, armed with the doctrines that He taught them, and which the Holy Spirit reminded them of and the truth which the Spirit lead them toward. He gave them absolute authority over sin, and to bind and loose “whatever.” Does your current community have that?
Wonderful, irreplaceable, but a sub-set of the Church - NOT it’s foundation.
