Sermon in a Sentence: St. Thomas Aquinas (April 15, 2014)

“Since evil is opposed to good, the presence of all good requires the utter banishment of evil. Justice has no participation with injustice, and light has no fellowship with darkness.” –From “Sermon in a Sentence: A Treasury of Quotations on the Spiritual Life; Vol. 5: St. Thomas Aquinas,” pg. 82. Selected and Arranged by John P. McClernon.


This is a pertinent reminder that in order to possess God, we must not harbor any attachment to evil. Some act as though this were the case, that even though they may have some pet sin or some sinful acquaintance with some person, they may hope, without giving these things up, to attain heaven. How can this be so? If God is the Greatest Good, and evil is opposed to good, how then can we claim that God will, for our sake, allow us some evil attachment so that we may share in His goodness? It simply does not obey reason, which God has given to us, and which elevates us above the other creatures so as to be created in His image. Did God not give us reason for a purpose, yes, even for this purpose, to know good from evil so that we may attain our Greatest Good and avoid the greatest evil, which is the loss of God? How can He Who is Goodness Itself have any part of evil? How can He allow it in His servants?

No, my friends; we must not allow ourselves to be deceived. We know that God has created us in His image and wishes for us to walk in His way. Our Lord tell us that we must be perfect, as our Father in heaven is perfect. If it is goodness for which we strive, and especially that Greatest Good which is the possession of God forever, we must utterly banish all evil and any attachment to it from our hearts and souls. We cannot love evil and expect to love and attain to good as well. The two are as oil and water–they cannot dwell together in the same vessel.

Let us remember this and reflect upon this as we prepare this Holy Week for the glorious resurrection of Christ on Easter Sunday. Let us strive to detach ourselves from our evil inclinations and banish all evil influences in our lives, that we may greet our Risen Lord with pure hearts, earnestly desiring His goodness and the possession of Him Who is Goodness Itself.
