John Chrysostom

Dost thou wish, he says, to be cheerful, dost thou wish to employ the day? I give thee spiritual drink; for drunkenness even cuts off the articulate sound of our tongue; it makes us lisp and stammer, and distorts the eyes, and the whole frame together. Learn to sing psalms, and thou shall see the delightfulness of the employment. For they who sing psalms are filled with the Holy Spirit, as they who sing satanic songs are filled with an unclean spirit.
