The book of the Acts of the Apostles, after the gospels but before the epistles, is real life history of the early church. No apostle was called “Father” or “priest” in the book of Acts. Moreover, after the day of Pentecost in which Mary was mentioned, no mention of her in the book of Acts.
Which goes to prove the entire Romish system is an unbiblical cult. No wonder they are so against sola scriptura.
The gospel of John was written as a directly evangelical book (its ending says so) and this was penned at a late date. Nothing more than this witness of John is being claimed as being needed for its purpose (and John still witnesses today through this book).
And yet, Christendom ultimately rests not on doctrines but on the person and promise of the Lord. This is a difficult thing for evangelicals to grasp, but once they do they will have more respect for the Roman church even while disagreeing with the things it teaches.
