As Tim Keller points out in The Prodigal God (Dutton, 2008), the parable of the prodigal son should have a plural in its name: sons. We all know of the younger brother's libertine living, but the elder brother has a more subtle problem: He is self-righteous and lacks joy.
Part of the evangelical political problem in contemporary America is that much of the press and public sees us as elder brothers. Sometimes we are that way in reaction to younger brothers. Sometimes younger brothers go their way in reaction to us.
In higher education, younger brother colleges are party schools that proffer sex and stimulants. Some Christian colleges try to avoid that by imposing tight rules in elder brother fashion. Those rules may lead to external conformity rather than deep belief. Both younger brother and elder brother colleges divert students from learning more about God.
In journalism, younger brother magazines ranging from Rolling Stone to People sell a continuation of younger brother college life. Elder brother reporters tend to be self-righteous fault-finders—and it's always someone else's fault. Elder brother journalism lacks love, charity, compassion, and a sense that all of us are in this mess together. Christian publications that look only at sin among secularists can also be elder brothers.
In the realm of "social justice," younger brothers want governmental redistribution so that everyone, regardless of conduct, gets part of the national inheritance. Some recipients of Washington's largesse are widows and orphans, but others are younger brothers or sisters who should go home but do not because government checks allow them to keep destroying themselves. Elder brothers, though, wax sarcastic about wastrels while they overlook the needy. "Social justice" turns into either social universalism or Social Darwinism.
The gay rights debate is another younger vs. elder brother combat zone. While covering Manhattan's annual humongous Gay Pride parade I didn't see any lip-locks except when the marchers observed a dozen souls from a church waving Bibles and screaming at them, "You're going to hell, sodomite" or "You're an abomination in the sight of God." The presence of elder brothers allowed younger brothers to feel self-righteous: ironically, ranting reminders about sin provided the opportunity to forget about sin.
