Augustine’s Paradigm ’ab exterioribus ad interiora, ab inferioribus ad superiora’ in the Western and Eastern Christian Mysticism

I argue that St. Augustine of Hippo was the first in the history of Christian spirituality who expressed a key tendency of Christian mysticism, which implies a gradual intellectual ascent of the human soul to God, consisting of the three main stages: external, internal, and supernal. In this ascent a Christian mystic proceeds from the knowledge of external beings to self-knowledge, and from his inner self to direct mystical contemplation of God. Similar doctrines may be found in the writings of the Greek Fathers. Although there are many similarities in the overall doctrine and in particular details between them, it does not imply the direct impact of Augustine’s theological thought on the Greek Fathers but rather the influence of the Neoplatonic philosophy on both Western and Eastern Christianity, in particular, of Plotinus’ theory of intellectual cognition.
