St. Matthew’s Gospel ends with well-known words, the so-called Great Commission. Jesus says, “Therefore go and make disciples of all the nations.”

There’s been a tremendous tension in American Christianity for the last half-century or more about the purpose of the church. The tension is sometimes presented as “mission” versus “maintenance.” Some churches and pastors are “missional,” meaning they want to make disciples. “Maintenance” churches and pastors don’t care about that, they just want to exist for themselves. Those are the caricatures.

The mistake in this way of thinking is that being a disciple is a binary thing, either you are or you aren’t. The switch is on or off.

It’s more complicated than that. The words St. Matthew put at the end of his Gospel say a little more: “Therefore go and make disciples of all the nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, teaching them to observe all I have commanded you. And lo, I am with you always, even to the close of the age.”

Baptism begins the life of the disciple, and it is accompanied by a continual teaching, an ongoing catechesis to observe everything Jesus commanded….

In his book The Sermon on the Mount: The Church’s First Statement of the Gospel, David P. Scaer draws out the true teaching of Jesus, obscured by textual assertions that accommodated man’s tendency to justify himself: there is no place for anger in the life of a disciple of Jesus.

“One who is angry has taken to himself the prerogative that belongs to God alone. The phrase “without cause” does not belong to the original reading. Even if there is a cause for anger, anger must be put aside among the followers of Jesus. There is no cause for anger. Though anger is the prerogative of God alone, in his work of reconciliation in Jesus he has set aside this anger. This makes the offense of anger even more repugnant. By becoming angry the one who claims to belong to Jesus and to know his mind takes an attitude diametrically opposed to God, who is no longer angry. The refusal to be reconciled is the sign that the person no longer belongs to Jesus and from God’s point of view is no longer a member of the community. Here is where excommunication becomes operative.”

Jeffrey Gibbs’ excellent article “The Myth of Righteous Anger” expands on this and is highly recommended.
