The Catholic Church is the steward of scripture. God started one church, the Catholic Church.
Yeah, Jesus talked of it, the Catholic church is the third steward. Matt 24:13-30. He hid his charge in the ground as well, preferring instead his ideas.
What!? That is a mere assertion, and not at all an answer to the question which your assertion requires to be answered. This is the third time, so either answer it or admit you cannot give an actual answer, and thus the often repeated we-gave-you-the-Bible assertion has no real weight.
For if it is to have any real import, it seems to be arguing that being an instrument and steward of Scripture makes such the infallible authority on it, so that those who dissent from these stewards are rebels against God. If not, then why invoke? Affirm or deny?
