The Christian life is not easy, but it actually is simple. When we clearly understand what sin and holiness are, then our choice to turn away from sin and be holy becomes clear, too.
The Scriptures and all the liturgical services of the Orthodox Church include the theme of spiritual warfare, but it is particularly prominent in the liturgical services for the martyred saints.
Why put these resurrectional themes into a psalm about judging the gods, about putting the fallen angels in their place and working justice upon them? It is because the whole cosmic narrative of the Scripture is about the war begun by these fallen ones against God.
The targeted demonic attacks we experience especially in this holy season are real, and we can spot them because of how they are so specifically designed to pull us away from participating in it. But these things do indeed come out by prayer and fasting.
How does the study of myth and legend contribute to mankind at a time like this? Are there are not starving people to feed, injustices to be set right, and cults of evil to be put down?
The cosmic war between God and His enemies the fallen angels is going on all around us and even within us. And we have been given the Cross, the very Staff of God, as a weapon against the demons.
However you want to understand why there are demons on the earth even now, it is true that they are real and they are present. It is true that the suffering of this world is closely associated with their activity.
