For as teaching without doing condemns the teacher so doing but not guiding others, lessens our reward. One ought therefore to be chief in either work, and having first set one`s self right, thus to proceed also to the care of the rest.
-St. John Chrysostom, Homilies 15 and 16 on Matthew 5, 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
