You mean there was no OT people could read to find truth like Paul told Timothy to do?
Not in the sense of picking up a book from a bookshelf and opening up to read it, no.
The scrolls of the Old Testament were kept in big rooms called Scriptoria. (singular: Scriptorium) They were huge. One scroll of the Scriptures (there were at least 46 in total) would have been about the same square footage as of your living room rug. Not exactly portable.
The majority of ordinary people heard them read out in the synagogue or at the Temple. Learned men like St. Paul and St. Timothy could go to the Scriptorium, take a scroll, and read it there, but it wasn’t something they could take home and read. Of course, those who regularly went to the synagogue would have been familiar with most of the Old Testament, and would have been able to quote it from memory, because of hearing them repeated so often.
Once they had heard the oral tradition of the Apostles - the sayings of Jesus, the things He did, and the story of His life, death and resurrection - they would have been able to make the connection to the various prophecies of the Old Testament - but nobody could have come up with the story and sayings of Jesus from the Old Testament alone - they would have had to hear the story from the Apostles, first, before they could understand the connections.
Jesus it the literal physical incarnation of the word of God.
Right. Jesus is the physical incarnation of the Word that came forth from the Father’s mouth to create all that exists.
He is
not the physical incarnation of a book. Nor is the Bible a physical incarnation of Jesus.
There is no correlation between the Bible and Jesus, even though both of them are called “the Word of God.” They are two entirely different expressions of God’s Word. The Bible is neither your Creator nor your Saviour.
I don’t think I Corinthians 12 is the right one.
There are many quotes in the New Testament that describe the Church as the mystical body of Christ. You could get out your Strongs, turn to “Church” in the index, and just start looking them up, I think.
