RE: If you’re a biblical Christian, you believe in sacred tradition.
Actually, if you’re a Biblical Christian, you should look at tradition in light of Sacred Scripture.
That’s not what Sacred Scripture says.
Gal 1:9ff But even if we, or an angel from heaven, preach any other gospel to you than what we have preached to you, let him be accursed. As we have said before, so now I say again, if anyone preaches any other gospel to you than what you have received, let him be accursed.
