For as persons not even knowing where to put a step forward, so they sat, overtaken by the darkness.
-St. John Chrysostom, Homily 14 on Matthew 4, 4th Century
Take heed, then, often to come together to give thanks to God, and show forth His praise. For when ye assemble frequently in the same place, the powers of Satan are destroyed, and the destruction at which he aims is prevented by the unity of your faith.
-St. Ignatius of Antioch, Epistle to the Ephesians Ch. 13, 2nd century
