Exactly. Because otherwise you'd have to admit it is an extra-Biblical doctrine that comes from the Church whose authority you deny.
But, it isn't. All the foundations are in the Bible. You don't even see what you're promoting, do you? Based on your reasoning, you're promoting the traditions of man over the God-inspired Bible.
Mar 7:6 And he said to them, “Well did Isaiah prophesy of you hypocrites, as it is written, “‘This people honors me with their lips, but their heart is far from me;
Mar 7:7 in vain do they worship me, teaching as doctrines the commandments of men.’
Mar 7:8 You leave the commandment of God and hold to the tradition of men.”
Mar 7:9 And he said to them, “You have a fine way of rejecting the commandment of God in order to establish your tradition! (ESV)
2Ti 3:15 and how from childhood you have been acquainted with the sacred writings, which are able to make you wise for salvation through faith in Christ Jesus.
2Ti 3:16 All Scripture is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness,
2Ti 3:17 that the man of God may be complete, equipped for every good work. (ESV)
The Bible is secondary. If the Church is the appliance, the Bible is the manual, so to speak.
And, here it is--"The Bible is secondary." The Bible
must be primary or you should just throw it out. You're teaching the same belief as Mormons, JWs, and Word of Faith and Charismatic types who reject what the Bible says in favor of their own beliefs and "revelations"--the doctrine of the "Church" trumps Scripture.
The Church
must be subservient to the Bible, or the Bible is pointless. One could make up all sorts of nonsense, like the immaculate conception or perpetual virginity of Mary.
Gal 1:8 But even if we or an angel from heaven should preach to you a gospel contrary to the one we preached to you, let him be accursed.
Gal 1:9 As we have said before, so now I say again: If anyone is preaching to you a gospel contrary to the one you received, let him be accursed. (ESV)
Even the apostles were subject to what was spoken and, therefore, written.
What did Jesus do when he confronted the Jewish leaders of his day?
He appealed to Scripture,
not his own authority, even though he is God incarnate. The Catholic and EO churches have put the cart before the horse, claiming the authority that the Jewish leaders claimed over the Scriptures. Jesus corrected it, but your church decided to go back into error.
Many people are only barely literate, if not completely literate. Even less are Biblical scholars. Do you even know any Greek?
What does this have to do with anything?
