The Catholic Official Interpretation of the Gospel Reading as a Reference to Original Sin

Gospel reading is taken from Matthew chapter 10, verses 26 through 33. We're going to focus on three details in this passage. Do not be afraid of those who killed the body, but cannot kill the soul. You are worth more than any than many sparrows. Everyone who acknowledges me before others, I will acknowledge before my heavenly father, but whoever denies me before others.
