Luke 9:7-9
The Church teaches that there is what we call “conscience” in every human person. “For man has in his heart a law written by God. To obey it is the very dignity of man; according to it he will be judged” (Gaudium et Spes, 16). The existence of conscience is also affirmed by Saint Paul when he said that even those who have no faith can do what is required by the Law because the demands of the Law are written in their hearts (Romans 2:14).
The person who does evil would not find peace because his conscience will constantly bother him. This is the experience of Herod as narrated by today's gospel. Upon hearing about Jesus, he remembers John the baptist whom he ordered killed and beheaded. He is bothered and perplexed because people are saying that Jesus is John raised from the dead. In contrast, the Church teaches that a good and clear conscience would bring peace and joy to a person. This, of course, is easily proven by experience.
Today's gospel inspires us to possess the virtue of integrity of conscience. We are challenged to nourish and educate our conscience by studying Catholic teachings or the demands of the Law. The traditional practice of daily examination of conscience remains highly recommended for Christians. Regularly, we try to check how we have failed or fulfilled the dictates of a good conscience. Such is the secret of a righteous and meaningful life.
