‘A History of Christianity’ marathon

New on Sunday, Mar. 14 from 9 a.m. to 6 p.m.

The first truly global history of Christianity, this six-part series is presented by Diarmaid MacCulloch, an Oxford history professor whose books about Thomas Cranmer and the Reformation have been acclaimed as masterpieces. A History of Christianity reveals its true origins and delves into what it means to be a Christian. Intelligent, thought-provoking and magisterial in scope, the series will uncover how a small Jewish sect that preached humility became the largest religion in the world.
