It is "illogical" to say that the teachings of Jesus Christ revealed to New Testament prophets were preserved in sacred Scripture in the same manner as the prophets of the Old Testament were? Of course the Apostles never used a Bible as we know it, who ever said they did? They COULDN'T have, could they? Yet, the "noble Bereans" were commended because they "searched the Scriptures daily" to ensure what the Apostles were preaching was true. Now what "scriptures" could Paul have been speaking of?
It is illogical to say they had the Bible when they didn’t.
