Fr. Stephen Freeman has written another excellent post on knowing God. I think Fr. Stephen has the best Orthodox blog in the blogosphere. The following is just a taste of what he has to say about our knowing God.
“There is a passage in one of my favorite spiritual novels, A Pilgrimage to Dzhvari, (written by the mother of Bishop Hilarion Alfeyev). In it, a mother and her son make pilgrimage to a monastery in Georgia (the one south of Russia). The woman is bright, intelligent and a fairly recent convert to the faith (having been previously a non-believer). In a conversation with the Abbot, she asks some questions about a passage in Maximus the Confessor. The Abbot reacts with alarm, “You’ve been reading the Fathers?” She replies in the affirmative. He is concerned that she may have done herself damage. “You should never read more hours in a day than you pray,” was his admonition.
His concern is that she not come to a place of imbalance - where the knowledge that fills her mind outstrips the knowledge that fills her heart. Such knowledge, acquired without ascesis (prayer, fasting, repentance, etc.) is the knowledge of which St. Paul warns when he says, “Knowledge puffs up” (makes us proud). It is by no means a celebration of ignorance, but rather a deeper diagnosis of precisely the kind of ignorance that poisons our souls.” Read more here.
