Austin Marsden Farrer was a theologian and philosopher whom many consider to be an outstanding figure of 20th century Anglicanism. He served as Fellow and Chaplain of Trinity College, Oxford, 1935–1960.
He was the progenitor of the eponymous "Farrer hypothesis" suggesting that the Gospel of Mark was written prior to, and influenced, those of Matthew and Luke, in contradistinction to the "Q" theory of textual analysis more widely held outside Britain.
This was less a reading-a-day as the name would suggest, and more "here are two or three passages for each week of the year," which was a tad disappointing and made it hard to keep up with. Nevertheless, it has its good parts and I used it for at least two or three devotionals at work.
