Glossa Ordinaria
Catena Aurea · Matthäusevangelium 6
But when ye pray, use not vain repetitions, as the heathen do: for they think that they shall be heard for their much speaking. Be ye not therefore like unto them: for your Father knoweth what things ye have need of, before ye ask Him.
(ord.) What He condemns is many words in praying that come of want of faith; as the Gentiles do. For a multitude of words were needful for the Gentiles, seeing the dæmons could not know for what they petitioned, until instructed by them; they think they shall be heard for their much speaking.
