In Brennan Manning’s Abba’s Child, he points out the time when Jesus asked us to be perfect, as our heavenly father is perfect. The word translated perfect is actually about being compassionate. Be compassionate, the way the father, the creator whose image we were made in, is compassionate. He gives the example of having been asked by an evangelical, while serving in the Regional AIDS Interfaith Network in New Orleans, what the posture of the Christian community ought to be toward the gay community.
His response was to cite the parable given by Jesus about letting the weeds grow up with the wheat. If we tear out of our community what we perceive to be weeds (note, I said perceive, for even Manning says we cannot know a person’s motive), we will tear out the wheat right along with it. When we presume to stand in God’s judgment seat, rather than his mercy seat, we do great damage. Ironically, after Romans 1, which includes a discourse by Paul against all kinds of sins, including sexual sins, he says we therefore have no right to judge anybody. Why would he say that unless he believed we all fall short of the glory of God just as much as we all have hope in being saved by him?
