Amen, I say to you, until heaven and earth pass away, not the smallest letter or the smallest part of a letter will pass from the law, until all things have taken place (Matthew 5:18).
Who doesn’t know life can change in a moment? A doctor explains an MRI result to a young woman. An employer hands out the proverbial pink slip. A spouse walks away from a marriage. A parent from a child. Like a train rumbling toward us, life happens. Change happens. It’s only a question of when change will arrive at our station.
That’s why this text in Matthew's gospel can be a comfort. When life quakes around us, God’s word is an immovable rock. When the runaway locomotive races at us, God stands at our side. When we doubt God will forgive sin, Scripture’s promise stops that train dead in its tracks.
As change roils through our culture -- even through many churches - the unchanging word of God provides a solid foundation of truth. In the midst of cultural and religious upheaval, where definitions of sin shift with popular opinion, Catholics can find the stability of moral certitude as the Church interprets sin and righteousness in the light of Scripture and Sacred Tradition. Through her guidance, we can know absolute and unchangeable truth from godless and deceptive error.
St. Paul reminded Timothy, the Church is "the pillar and support of the truth" (1 Timothy 3:15). And the Psalmist wrote, “Your word, Lord, stands forever; it is firm as the heavens. Through all generations your truth endures; fixed to stand firm like the earth” (Psalm 119:89-90).
Isn’t it good to know some things never change?
