That is spiritual naivety. These men were not running away, they devoted their lives to striving to know God and praying for others. Without the Desert Fathers they'd likely be no Athonite Saints, or monasteries for that matter. Orthodox Elders and Saints have inspired many thousands to turn to Christ with their hard earned wisdom and knowledge of The Way. The Elders and Saints are an inspiration to me and have held me up when I felt like giving up. There's nothing more valuable to me right now than the writings and teachings of the many hesychasts and monks who, through great sacrifice and devotion, illuminated The Way. And God only knows how much their prayers of intercession have helped others.An Orthodox friend gave me the Desert Fathers to read and I never got warm with them, because they were running away. Christ and the Apostles faced persecution. And it is non-practical to run away, because one day there is no more place to run to.
