I'm stealing this idea from Barbara Nicolosi (Church of the Masses). She has "Emily Monday," in which she posts thoughts from the great poet. On Thomas Tuesday, I'll post thoughts from St. Thomas Aquinas. I'm starting with The Compendium of Theology, also called the Shorter Summa. In this work, Thomas synthesizes themes from his larger work, the Summa Theologiae.
"Faith is a certain foretaste of that knowledge which is to make us happy in the life to come. ...
Our Lord has taught us that this beatific knowledge has to do with two truths, namely, the divinity of the Blessed Trinity and the humanity of Christ. That is why, addressing the Father, he says, "This is eternal life: that they may know you, the only true God, and Jesus Christ, whom you have sent." All the knowledge imparted by faith turns about these t wo points, the divinity of the Trinity and the humanity of Christ."
(from chapter 2)
My comment: notice that St. Thomas sees happiness in heaven in terms of knowledge of God, a loving knowledge.
