"from beneath, out of the heart, draw forth a voice, make thy prayer a mystery. Seest thou not that even in the houses of kings all tumult is put away, and great on all sides is the silence? Do thou also therefore, entering as into a palace not that on the earth — but what is far more awful than it, that which is in heaven —show forth great seemliness.
Yea, for thou art joined to the choirs of angels, and art in communion with archangels, and art singing with the seraphim. And all these tribes show forth much goodly order, singing with great awe that mystical strain, and their sacred hymns to God, the King of all. With these then mingle thyself, when thou art praying, and emulate their mystical order.
For not unto men art thou praying, but to God, who is everywhere present, who hears even before the voice, who knows the secrets of the mind. If thou so pray, great is the reward thou shalt receive.”
- St. John Chrysostom, Homilies on the Gospel of St. Matthew
