The Bible: Written Revelation
The Word of God revealing Himself to His People through
the sacred authors was first of all oral. Periods of oral
transmission varied.
The revelation of Genesis, from prehistory to the time of Moses
is an example of oral transmission.
The period from the resurrection and ascension of Jesus
(about 30 AD) until some of Paul's letters (about 51 AD) or
the writing of the first Gospel, Mark's (about 65 AD), is another
example of oral transmission of revelation.
