The March for Life today is a indication of a New Reign. The Mass readings for today weren’t chosen for the March, but they support this.
Our Gospel from Mark simply recounts the names of the Twelve Apostles. This might not seem significant, but this marks a New Reign. The Twelve replace the twelve tribes of Israel to bring forward the Kingdom of God.
But then our Old Testament reading recounts how David had the opportunity to kill Saul, but spared his life. All this after Saul had been pursuing David to kill him. David would eventually replace Saul with a new reign, but it would be of an entirely different character. Saul was murderous, like most worldly leaders, jealous to preserve his power. But David’s stood for life, and his reign would be of an entirely different character.
Likewise, the Twelve disciples bring forward the gospel, which is the gospel of Life. Like David, they were far from perfect. But their heart was to follow God above all.
Like the Twelve chosen by Jesus and young David, the youth who march today are still getting their sea legs in the faith. They are far from perfect, but they are marching with a heart for God. This is all they need to bring forward the New Reign of the Kingdom of God. A Kingdom based on mercy, and Kingdom of Life.
