Greetings in that Divine and Most Precious Name of Our Lord and Savior Jesus Christ!
No "?" about it: the Church has been interpreting the Bible for thousands of years. But of course, such types don't like authority, besides their own that is.Trying to convey this to my protestant dad has been such a struggle for me, because he relies on the Bible's authority and not on some church.
I really need some help with this.
For this, prayer is the only answer. If simple logic
doesn't convince folks that the source of the authority of the Scriptures is in the Church which authored, copied, and transmits these Scriptures over the past thousands of years, then it truly takes only a miracle of God
Even if you were to draw out the long, intricate, and complicated history of Biblical scholarship in the Church, traced the evolution of the Canon and the various translations, incorporated the influence of the Patristic commentaries, and included the archeological, historical, and cultural evidence of the Church being the perpetual source of the Bible, I'm sure your father and many others would hardly be convinced. They would essentially cry conspiracy and instead draw back upon their previous inclinations, because their ideas are not based on any kind of fact or reality in the first place, and being contrary to reason they should be considered obviously unreasonable. As such, you should not worry yourself with unreasonable people aside from a prayerful effort for God to convince the hearts of some to see the Truth in His time. After all, if folks do acknowledge the Scriptures, then they are at the least half way there already
