Do you believe in sola scriptura?
Most Protestants who believe literally only in what the Bible teaches, refuse to believe literally that Jesus founded the Church on St. Peter (Matthew 16:17-19), that Holy Communion is truly the Body and Blood of Christ (John 6:32-69)and not just a memorial, that Jesus gave His apostles the power to forgive sins (John 20:21-23), and in the intercession of the saints in heaven (Revelation 5:8; Revelation 8:3-4). As a former Protestant, I am constantly amazed how Protestants who will not believe anything unless it is in Scripture conveniently ignore major teachings in that same Scripture. It can't be any more clear, but most Protestants say, "Oh, He didn't really mean that" when confronted with a point they don't like. One can't have it both ways. One either believes everything in Scripture, or one doesn't. And one can't say "Oh well, Jesus didn't mean that." There is no way to know that He didn't mean whatever He said unless one has some sort of insight into the mind of God. That is the most presumptious thinking imaginable. If Holy Scripture is inspired by God, then the words of Jesus are accurately recorded and He meant exactly what He said. We also know that He meant what He said because the first Christians believed these things, too, and we can read their writings from the first, second, and third centuries.
