Rufino de Aquilea
Origen is considered by some Christian groups to be a Church Father though he does not have this status in Orthodox Christianity. He is widely regarded as one of the most influential Christian theologians. His teachings were especially influential in the east, with Athanasius of Alexandria and the three Cappadocian Fathers being among his most devoted followers. Argument over the orthodoxy of Origen's teachings spawned the First Origenist Crisis in the late fourth century, in which he was attacked by Epiphanius of Salamis and Jerome but defended by Tyrannius Rufinus and John of Jerusalem. In 543, Emperor Justinian I condemned him as a heretic and ordered all his writings to be burned. The Second Council of Constantinople in 553 may have anathematized Origen, or it may have only condemned certain heretical teachings which claimed to be derived from Origen. His teachings on the pre-existence of souls were rejected by the Church.
