How did Origen influence Evagrius Ponticus and John Cassian?

Origen was a seminal figure in the development of early monasticism, and his theological ideas were transmitted to later generations primarily through the writings of Evagrius Ponticus.1

Evagrius developed the first major philosophical-theological exposition of monastic mysticism by building upon Origen’s Neoplatonic biblical theology. He integrated Origen’s concepts into his own spiritual doctrine, which emphasized the soul's journey toward union with God through asceticism and the mastery of the spirit over matter.2

Through the works of Evagrius, these Origenist ideas were passed on to John Cassian, a 5th-century monastic writer who introduced them into the Western Christian tradition. While Origen’s influence was profound, it was also controversial; both Evagrius and his teachings were later denounced by the second Council of Constantinople in 553 for containing what were perceived as Origenist errors, such as the doctrine of the preexistence of souls and subordinationist views regarding the Trinity.21
