In this video Dr. Costa addresses the writings of St. John Climacus which speak of Eastern Orthodox monks praying among other things to be possessed by devils / demons! Is this biblical? What does this have to do with the Gospel? St. John of the Ladder, also known as St. John Climacus, was a 6th-7th century Christian monk and abbot of St. Catherine’s Monastery on Mount Sinai. His work 'The Ladder of Divine Ascent,' is a highly influential spiritual guide detailing the thirty steps to spiritual perfection.
