The italicized portion appears to presuppose that before scriptural cannon was set that the scripture was not written until the 4th century. In fact the books the Catholic church cannonised were completed before the end of the first century and were being read by the first generation of believers of the apostolic era. Church fathers of the second century clearly accepted the books that were not canonized until 2 centuries later. Augustine and many others writings include documents they rejected. The only reason the Catholic church adopted a cannon in the 4th century was in response to various groups attacking the books that had been viewed as scripture since the apostolic era.
Just look at how well the Pharisees and Saducees fairer by holding tradition equal to or greater than scripture. The very Messiah that scripture pointed to, they rejected. They were more worried about their tradition regarding the Sabbath then what scripture said. They were engulfed with enlongating their phalacteries and praying in public so people could see how righteous they were.
And somehow 2000 years later tradition is supposed to work better for us. Are we better people in God’s eyes because we hold to tradition? Or post that first Easter, does scripture tell us that God sees us as righteous people through the lenses of the fulfillment of all things His Son Jesus. Jesus who the the writers of the new testament confess.
What people are NOT addressing is what Tradition IS.
Tradition is TRUTH that we hold to be truth from the
beginning. Therefore if the Apostles baptized by sprinkling
or immersion, with living or with cold water, a decision based
entirely on water resources available in the desert or Rome
at the time- such baptismal practice is a Tradition
and a TRUTH for it is TRUTH that they baptized
both ways according to water availability and we know
this how? From OTHER writings of people familiar with
them as peers.
Yet no where in Scripture does it say baptize by immersion
or by sprinkling, no where in the Bible does it state
use living or cold water, or what to do when the Jordan
dries up to a mudflat.
Tradition just IS, like TRUTH just is. It just is.
To claim anyone pharisaical over the matter by holding
to tradition is false because it is like saying what is
truth can be conveniently altered at will.
So no those who cling to tradition in these issues
are NOT the Pharisees- but quite likely their
detractors are.
