Can you point us to the INFALLIBLE interpretation of the entire bible by the magisterium ...
Read the decrees of the ecumenical councils. I know you reject all of them, so Tritheism, Subordinationism, Nestorianism, Pelagianism, Semi-Pelagianism, Monophysitism, etc. are perfectly OK.
Right? Let’s do the right thing and ignore the Church’s interpretations when it condemns Arius, Donatus, etc.
Anytime you interpret the scriptures excluding Arian, Nestorian, Tritheist, etc. interpretations, you are adhering to Tradition.
I might add Evangelicalism is steeped in as much TRADITION as Roman Catholicism or Eastern Orthodoxy except you resort to denials and appeals to ignorance whenever anyone raises it.
Everything you believe in is TRADITION. Had you been raised a Lutheran, you’d be spouting similar rhetoric, but be using different arguments.
Sola Traditio.
