Jesus offers his peace to his disciples as an alternative to the peace that the world offers. Although Jesus does not explain how his peace differs from worldly peace, he gives a clear indication in that regard at the beginning of his public ministry. Soon after his baptism, Jesus enters the synagogue and characterizes the purpose of his mission in a way that connects his peace with justice. Jesus makes that connection when he quotes a passage from Isaiah to those gathered: “The Spirit of the Lord is upon me, because he has anointed me to preach good news to the poor. He has sent me to proclaim release to the captives and recovering of sight to the blind, to set at liberty those who are oppressed…” (Lk 4:18; Is 61:1).
A succinct version of this same characterization is found in Psalm 85, which reads: Near indeed is his salvation for those who fear him; glory will dwell in our land. Love and truth will meet; justice and peace will kiss (Ps 85:10-11). The implication is that the peace of Jesus is inseparable from justice. We cannot have one without the other. Jesus qualifies his offer of peace with justice not as a call to abandon the world, but to transform it. The peace that Jesus offers is therefore the outcome of right living, that is, living in a manner consistent with his values rather than the values of the world (Phil 4:8-9).
Paul appeals to this responsibility of ours in his letter to the Romans. In that letter, Paul claims that “the kingdom of God is not a matter of food and drink, but of righteousness, peace, and joy in the Holy Spirit; whoever serves Christ in this way is pleasing to God and approved by others. Let us then pursue what leads to peace and to building up one another (Rm 14:17-19). Realizing peace on these terms is the natural outcome of exercising justice in our relationships with each other.
The principle of justice extends beyond our relationships with each other, however. Because God created the world and all that is in it, including those who live here, everything in creation belongs to God (Ps 24:1). Therefore, despite long held views of our right to exploit nature’s resources however we see fit, we do not have such a right. The goods of the world do not belong to us; they belong to God.
For that reason, God calls us to exercise justice in our relationship to creation itself. This is a call to be good stewards of what belongs to God. On these terms, good stewardship is not a way of managing our possessions. Rather, good stewardship is paying attention to and caring for what God has entrusted to our care. Good stewardship is what God expects of us. He trusts us to be good stewards of his creation for ourselves and for those who come after us.
In short, justice and peace are not only a part of what Jesus came to do. Justice and peace are the heart of his mission on earth. For this reason, justice, peace, and integrity of creation are central to faithful living. Our relationship with each other and with God’s creation derives from a keen awareness and consistent practice of mutuality, solidarity, respect, and justice. If we follow the commandments of Jesus in this way, justice will indeed bring about peace, not just for some but for all (Is 32:17), and our peace will flow like a river (Is 48:18).
