New Series On Mark's Gospel

My recent study has caused me to revise my thinking on the date of Mark's gospel. For years I accepted what I was taught at Durham University in 1985, that Mark was written somewhere between 65CE and 80CE. I am now convinced it was much earlier as you will hear in my new series of sermons and be able to read in my forthcoming book. I now date it much earlier 42-44CE. This has a profound effect on my understanding of how setting down of the gospel record developed.
