The Stone Rejected: Building on the True Foundation

2Pt 1:2-7; Psalm: 90; Mk 12:1-12

Memorial of Saint Justin, Martyr

My dear Sisters and Brothers in Christ,

On this Memorial of Saint Justin, a philosopher who sought truth in many systems before finding it in Christ, the Word of God presents us with a parable that cuts to the heart of human resistance. The tenants in the vineyard reject the servants, then the son, in a desperate grasp for inheritance. Jesus quotes the Psalm: “The stone that the builders rejected has become the cornerstone.” Saint Peter, in his second letter, urges us to supplement our faith with virtue, knowledge, self-control, endurance, devotion, mutual affection, and love. These are the graces that shape us into living stones built upon the rejected Stone.

In the Gospel of Mark, Jesus tells a parable of violence and greed. A landowner plants a vineyard, leases it to tenants, and goes away. At harvest time, he sends servants to collect his share. The tenants beat one, kill another, stone a third. Finally, he sends his beloved son, thinking, “They will respect my son.” But the tenants see their opportunity: “This is the heir. Come, let us kill him, and the inheritance will be ours.” They kill him and cast him out. Jesus asks, “What will the owner do? He will come and destroy those tenants and give the vineyard to others.” The religious leaders recognize the parable is against them, but their hardness of heart prevents them from seizing the truth.

The rejected son is Jesus. The vineyard is Israel, and by extension, the Church. The tenants represent those who reject God’s messengers and finally His Son. But God does not abandon His vineyard. He gives it to others—to the Gentiles, to the Church, to us. And the stone that the builders rejected becomes the cornerstone, the foundation of a new temple. Those who reject it will be shattered; those who fall on it will be broken open to new life.

Saint Peter, writing to early believers, describes the process of becoming living stones. “Make every effort to supplement your faith with virtue, virtue with knowledge, knowledge with self-control, self-control with endurance, endurance with devotion, devotion with mutual affection, mutual affection with love.” This is the architecture of discipleship. Faith is the foundation, but it must be built upon. Virtue, knowledge, self-control, endurance, devotion, mutual affection, and love are the courses of stone that make us fit for the Kingdom. Without these, our faith remains a dead building block, unused and unusable.

Saint Justin, a second-century apologist, was a builder on the true foundation. He sought truth in Stoicism, Aristotelianism, Pythagoreanism, and Platonism before encountering Christ. He recognized that the Logos—the divine reason who became flesh—was the cornerstone that all philosophers had dimly perceived. He did not reject the stone; he built his life upon it. And when he was martyred for his faith, his blood became the mortar that strengthened the Church.

Pope Francis reminds us: “The stone rejected is the one that saves us. When we accept Christ, we become part of a new building, a new community.” St. John Paul II said, “Do not be afraid to be holy. Holiness is the measure of the Christian life.”

What does this mean for us? We are the tenants of the vineyard today. God has entrusted His Church to us. Do we reject the messengers He sends—the prophets of our own time, the saints, the poor, the inconvenient truth-tellers? Do we reject the Son by ignoring His presence in the Eucharist, in Scripture, in the needy? Or do we build our lives on the cornerstone? Do we supplement our faith with virtue, knowledge, and love? This Memorial of Saint Justin calls us to be builders, not destroyers. To receive the Son, not reject Him. To become living stones in the temple of God.

Let us pray for the courage to embrace the rejected Stone. Let us build our lives on the true foundation. And let us, like Saint Justin, witness to the Logos who is love, even to the point of giving our lives. Amen.

May God bless you all!
