This makes sense. I'm not sure that I can readily refute the proof-text given.Hello,
There is the classic "proof-text" of 2 Thessalonians 2:15.
"So then, brothers and sisters, stand firm and hold fast to the teachings we passed on to you, whether by word of mouth or by letter." The NIV translation (because it was on top of biblehub.com).
It is also translated as "whether by word or by epistle..." in the KJV. That is referring to the Magisterium of the Church. Look at Roosh himself for an example of this concept. His articles he writes are very insightful. Then watch his podcasts. There are things in his podcasts and videos that he never touches on in his writings, and vice versa. To understand Roosh's "full teachings" you have to look at both. It is no different than with St. Paul here. There is a lot of great teachings in writings, but that is not everything he taught to the earliest Christians. One needs to trust St. Paul's successors, the Bishops, all working together.
In many ways you already are submitting to the Magisterium of the Church. Do you believe that public Revelation stopped after the death of the last Apostle? That is a conclusion the Magisterium has come to. That is found no where in the Bible.
Do you believe in the Trinitarian God? The word "Trinity" is not in the Bible. That theological-concept is a conclusion of the Magisterium of the Church.
Your analogy makes sense to me. Although, as a Lutheran, I'd say that the concept of the Trinity is in the Bible, but perhaps the articulation of the concept can be credited to tradition.
I have no issue deferring to authority. I don't understand all of the Bible. We have the Book of Concord to which I defer, as I consider it to be Biblical...but I am beginning to have my doubts. Thank you for the reply.
