[Eric Lemonholm's] criticism [of the RCL] echoes others: “missing and disconnected texts.”
Lemonholm’s most striking example is “love your enemies.” The RCL actually assigns both Matthew’s version of that text and Luke’s. But in both cases it’s slated for the seventh Sunday after Epiphany, one of the Ordinary cycle’s odd benchwarming weeks—used only when the liturgical calendar’s stars align. Week seven didn’t make it into the Year A or C calendar between 2001 and 2011. “A ten-year absence of Jesus’ command to love our enemies occurred,” says Lemonholm, “during the first ten years of the war on terror.”
This Sunday, "love your enemies" is back in the lineup. But Luke's week seven was benched last year and will sit out again in 2016, so this week is the only time this particular double tradition saying will get the nod in a five-year span.
All of which is to say: if you're preaching or planning worship this week at a church that follows the RCL strictly, please resist the temptation to focus primarily on Leviticus or 1 Corinthians. Give us "love your enemies," because we badly need it—and while the text may strike us professional Christians as overfamiliar, those who encounter the Bible only in worship haven't actually been hearing it all that often.
