“ST. PAUL instructs us that our entire perfection is contained at present under three concise headings: and now there remain faith, hope, charity, these three (1 Cor. 13, 13). Such is the apostle’s order, such the order of reason, for we cannot love unless we have good reason to hope, and we cannot hope unless we have knowledge.”
~St. Thomas Aquinas: Compendium of Theology, 1.
