Times have changed, of course. Diaconal models in 16th-century Geneva won’t work in 21st-century America. Our economic, social, and political conditions forbid it. These days, talk of “justice” in the church is often either politicized according to a Right or Left agenda or, reacting to such politicization, silenced altogether. But by highlighting the true nature of Christ’s kingdom and the role of righteousness in the church’s mission, Calvin’s theology might help us avoid these extremes.

When John Calvin became pastor in Geneva, most Protestant churches didn’t have deacons responsible for caring for the poor. In the medieval church, the diaconate had become an office with largely liturgical responsibilities. Most Reformed churches, following Ulrich Zwingli and Heinrich Bullinger, assumed it was the state’s responsibility—not the church’s—to care for the poor.

Calvin decisively rejected all of these views. Identifying the church as Christ’s spiritual kingdom, Calvin insisted the church must witness to the justice and righteousness of Christ’s kingdom in its own way, in accordance with Christ’s commands. This meant, as one of the church’s essential ministries, it had to call men and women to serve in the spiritual office of deacon.

Justice, Not Charity

Calvin, like other Christians before him, believed God has given the earth and its resources to human beings. As those made in the image of God, we’re called to share our resources and serve one another. Calvin often used the language of rights to describe this principle. A person is defrauded, he argued, when a need is left unmet by someone with the power to meet it.

Caring for the poor, then, isn’t a requirement of charity but of justice, a basic demand of natural law. God is the “protector and patron of the poor,” Calvin says, the one who hears their cries and “feels himself injured in their persons.” Therefore, he won’t let their afflictions remain unavenged.

Government

Calvin believed one of the main responsibilities of civil government is to ensure the poor receive their rights. As he puts it in his commentary on Psalm 72:

God takes a more special care of the poor than of others, since they are most exposed to injuries and violence. . . . David, therefore, particularly mentions that the king will be the defender of those who can only be safe under the protection of the magistrate.

For that reason, a “just and well-regulated government will be distinguished for maintaining the rights of the poor and afflicted.”

The rich rarely need the government’s protection, yet the poor almost always do. Thus, Calvin preached, it is “praiseworthy for a good prince to relieve his subjects’ poverty.” He must do so not only by prohibiting practices such as unjust usury, but also by opening poorhouses, hospitals, and schools. Calvin believed all pastors should preach this command, for he saw it as the clear teaching of God’s Word.

Yet Calvin was no utopian. Just as humans fail to care for the poor, so government does little better. This is why it’s so vital for the poor to look to Christ as their true King who secures mercy and justice for them. It is ultimately to Christ that passages like Psalm 72 point, and only in the kingdom of Christ is true justice fully secured. Thus the gospel comes to the poor as especially good news.

Church

For Calvin, this is where the role of the church comes in. He viewed the church as the primary expression of Christ’s kingdom in this age. It is the arena in which Christ’s Word and Spirit are at work, regenerating men and women and knitting them together in solidarity. For that reason, the church must be the place where the poor find justice: “Except then we endeavor to relieve the necessities of our brethren and to offer them assistance, there will not be in us but one part of true conversion.”
