St. Gregory the Theologian, Oration 38, Section 5:
And how will this be? Let us not put wreaths on our front doors, or assemble troupes of dancers, or decorate the streets. Let us not feast the eyes, or mesmerize the sense of hearing, or make effeminate the sense of smell, or prostitute the sense of taste, or gratify the sense of touch. These are ready paths to evil, and entrances of sin. Let us not be softened by delicate and extravagant clothing, whose beauty is its inutility, or by transparency of stones, or the brilliance of gold, or the artificiality of colors that falsify natural beauty and are invented in opposition to the [divine] image; nor by “revelries and drunkenness,” to which I know “debauchery and licentiousness” are linked, since from bad teachers come bad teachings, or rather from evil seeds come evil harvests. Let us not build high beds of straw, making shelters for the debauchery of the stomach. Let us not assess the bouquet of wines, the concoctions of chefs, the great cost of perfumes. Let earth and sea not bring us as gifts the valued dung, for this is how I know to evaluate luxury. Let us not strive to conquer each other in dissoluteness. For to me all that is superfluous and beyond need is dissoluteness, particularly when others are hungry and in want, who are of the same clay and the same composition as ourselves.
