You cannot serve two masters—and that warning echoes across all three of today’s readings.

In Second Clement (Chapters 6–10), we are confronted with the stark opposition between this present world and the world to come: one urges greed, corruption, and compromise; the other calls us to holiness, endurance, and repentance. The homily presses us with athletic urgency—strive for the incorruptible crown, guard the seal of baptism, repent while the clay is still soft in the Potter’s hands (Matthew 6:24; Matthew 16:26; Isaiah 66:24; Luke 16:10). This is not casual Christianity. The present age is fleeting; eternal life belongs to those who keep the flesh holy and persevere.

Augustine, in Confessions 5.9 (Section 16), brings that warning into painful autobiography. Struck with fever and near death, he realizes he was on the brink of eternal judgment while still mocking Christ as a phantom and delaying baptism (Ephesians 2:16). His mother prayed, unaware how close he was to destruction, yet God heard her deeper prayer. Augustine sees that had he died then, he would have faced the fire his sins deserved. Even his sickness became mercy—God would not allow him to die a “double death.” The struggle between two worlds was not abstract; it was raging inside his own soul.

Then Aquinas, in Summa Theologica I.32.1, lifts our eyes higher. The Trinity—the very life of God—is not something reason can discover by examining creation. We can know that God exists and that He is good, but the inner life of Father, Son, and Spirit must be revealed. The world cannot reason its way into the Trinity. God must open the door. And He has. What Clement urges us to live, Augustine nearly lost, and Aquinas carefully explains: salvation is not speculation. It is revealed truth, received by faith, and guarded in obedience.
