St. Thomas Aquinas, Summa Theologiae, I-II, Q. 88, A. 5, Reply 1: “With regard to drunkenness we reply that it is a mortal sin by reason of its genus; for, that a man, without necessity, and through the mere lust of wine, makes himself unable to use his reason, whereby he is directed to God and avoids committing many sins, is expressly contrary to virtue.”
St. Basil the Great: “… I shudder at Sabellianism as much as at Judaism.” (Letter 189)
