“If you want to know anything about the Church and the Bible I refer you to the blueprint, it’s call the Catechism of the Catholic Church.”
So is this your final, final word?
Are you now trying to say you want to outsource supporting your claims?
Christ is the source of all truth, not a book. The Bible, as much as it might chagrin many Protestants to understand, is a historical record of the life and times of Christ as well as a summary of important geopolitical events that led up to His coming. It is not the penultimate handbook for Christianity and never has been; one searches the Bible in vain for a single verse that claims otherwise.
As you know, Christ did not instruct His disciples to go out and distribute Bibles to people. He told them to make converts, which was only done by word of mouth preaching. Bibles did not exist yet; the components of the Scriptures existed, but they were not gathered together until the Council of Rome in 38 - quite a bit of time after Christ, wouldn’t you say? Therefore, how can anyone believe the Bible is divinely inspired without the Catholic Church to say so? Even the most diehard Protestant who accepts a truncated Bible still assents to the Catholic Church’s infallible teaching on the matter when he or she believes the Bible is of God, because the Church was the first authority to proclaim that to people.
All our information about Christianity we have thanks to the Church, the Church Christ Himself gave us.
