Alexander's service was carried out to perfection, with God's help, and his disciples were far advanced in their faith. They took so much joy in their psalms and hymns and peaceful way of life that the Enemy was outraged at the sight, and went against the noble athlete like an army going to war.
Before armies charge at each other in unison with swords drawn, and victory goes to the stronger force, they fire missiles from far away, and that is how the Enemy began. For fifty years he had battled Alexander, and always the battle went against him, and the man remained unbroken. Now, for one last time, the Enemy joined all his demonic forces to a population he had recruited from humanity and, hurling his bolt against the slave of God, made his advance.
And so word went to the eparchs that Alexander the monk was a heretic, out to defile the church of God. But with his prayers to see him through, the blessed one's enemies couldn't even stand up to his shadow, so to speak. For it is in the nature of falsehood to be ruined by the truth. To state the truth opaquely, righteousness made it through the storm.
