The Epistle of Ignatius to the Ephesians (Long Version)

Take heed, then, to come together often to give thanks to God and proclaim His praise. For when you gather frequently in the same place, the powers of Satan are destroyed, and his "fiery darts" urging to sin become ineffective. Your unity and harmonious faith bring about his destruction and the torment of his followers. Nothing is better than the peace that is in Christ, which ends all conflict, both with spirits of the air and those on earth. "For we wrestle not against blood and flesh, but against principalities and powers, and against the rulers of the darkness of this world, against spiritual wickedness in heavenly places."
