Your wishful thinking does not make it true nor does repeating yourself over and over again.
Scripture is inherently authoritative and complete based on it's being the very Holy Spirit inspired, God breathed word of God.
It is Truth, and as such, stands on its own merit.
In the gospels and epistles, Jesus is reported to have commanded the apostles and disciples to TEACH, to BAPTIZE, to EAT HIS BODY AND DRINK HIS BLOOD. In other words, to hand on TRADITION and to confect SACRAMENTS. Jesus is not reported even once as suggesting that his teaching was to be written down—let alone that writings were to be the ONLY means of transmitting his teaching.
The diabolical doctrine of sola scripture is a human invention, part and parcel of a stunted, deformed, and relatively novel caricature of Christianity.
The weakest most contradictory argument I have heard from a Catholic yet. It is laughable that Catholics only do what is explicitly taught in the NT or OT or it is human-invented dogma . You can't make this stuff up.
