LN what part of the OP don't you understand? Would you like to discuss this one at a time-



The Word of God is Transferred Orally
Mark 13:31 - heaven and earth will pass away, but Jesus' Word will not pass away. But Jesus never says anything about His Word being entirely committed to a book. Also, it took 400 years to compile the Bible, and another 1,000 years to invent the printing press.

How was the Word of God communicated?

The answer is-Orally, by the bishops of the Church, with the guidance and protection of the Holy Spirit.

If you have another answer please tell us what it is
