This Sunday, Jesus tells a short, uncomfortable story. A father asks two sons to go work in the vineyard. One says no, but later goes. The other says yes, but never shows up. It is a parable so simple, we almost miss how sharp it is. Jesus is clear about who it is for. This is not aimed at pagans or outsiders. It is aimed squarely at religious people, people who know the right words and sound obedient.

Every December, the priests of my diocese gather for a Christmas dinner with our bishop. Nearly 200 of us in one room: newly ordained and long retired, pastors of large parishes and quiet confessors, men full of energy and others moving more slowly. Some carry visible success; others bear hidden wounds. It is a tapestry of vocations and lives. When the bishop thanks us, I am always moved. For a moment, none of our differences matter. What matters is that we belong to one another.

In my parish, there was once a new employee who frequently told me she was sorry for various imperfections in her work. It could be a little tiring. I finally told her, “You know, you don’t have to say ‘sorry’ so often.” She looked me right in the eyes and said, “Father, you’re right. I’m sorry.” Her ear-to-ear grin betrayed that she enjoyed the irony — and that she would keep asking for forgiveness as often as she needed it.

Jesus gives instructions for ministering to those persisting in error. Here’s the CliffsNotes version: If all else fails, “treat him as you would a Gentile or a tax collector.”

In other words? Don’t give up. Tell him the truth. Wash, rinse and repeat.

Technically speaking, I’m a Gentile. I’ve done those mail-in DNA tests, and none of my ancestors were Jewish. So whoever told my family about the God of Abraham, it wasn’t Moses, and it probably wasn’t Jesus himself, unless he spent some time in northwestern Europe that the Gospels fail to mention.
