I am in FULL agreement with Vicki's comments. There is grave spiritual danger in reducing the experience with satan to mere stories and glib commentaries. Talking about specific "encounters" with demons distracts us from a broader vigilance: when we dwell on "encountering" satan in a physical and tangible sense, we lose sight of how our enemies permeate the world we live in, and thus we are less vigilant and more susceptible to the subtle methods the evil one uses to distract us from our goal, which is Theosis.
As Orthodox Christians, we are NOT spiritual "free-agents." Rather, we seek the spiritual direction from our Spiritual Fathers and Mothers, and the wisdom of patristic teachers. Any matter of grave spiritual concern must be vetted through the Church and Her representatives, or we risk falling into the sin of pride. Similarly, we too fall into the sin of pride by posting here on the internet, usually without the prior knowledge or consultaion with our Spiritual Fathers.
Remember to live in the world, and not be of the world. We are mere sojourners here...we must forever focus on God and His Will, and on our Heavenly home. We do not fear the evil one, because he has been defeated, but we continue to be vigilant and aware that we are susceptible to his wiles. This way, we reinforce and steady our defences, and stiffen our resolve to follow Christ. We believe in satan, we are vigilant in both discerning his presence and influence, we seek to discern the Will of God, and we seek to continue our path to Theosis by following God's Will. These are very serious matters, and we must approach them with due gravity.
