Melvyn Bragg and guests discuss the form of Christianity adopted by Ostrogoths in the 4th century AD, which they learned from Roman missionaries and from their own contact with the imperial court at Constantinople. This form spread to the Vandals and the Visigoths, who took it into Roman Spain and North Africa, and the Ostrogoths brought it deeper into Italy after the fall of the western Roman empire. Meanwhile, with the Roman empire in the east now firmly committed to the Nicene Creed not the Arian, the Goths and Vandals faced conflict or conversion, as Arianism moved from an orthodox view to being a heresy that would keep followers from heaven and delay the Second Coming for all.
