In my opening address at General Convention, I spoke about the "great Western heresy" of individualism (see the full text here). There have been varied reactions from people who weren't there, who heard or read an isolated comment without the context. Apparently I wasn't clear!
Individualism (the understanding that the interests and independence of the individual necessarily trump the interests of others as well as principles of interdependence) is basically unbiblical and unchristian.
The spiritual journey, at least in the Judeo-Christian tradition, is about holy living in community. When Jesus was asked to summarize the Torah, he said, "love God and love your neighbor as yourself." That means our task is to be in relationship with God and with our neighbors. If salvation is understood only as "getting right with God" without considering "getting right with (all) our neighbors," then we've got a heresy (an unorthodox belief) on our hands.
The theme of our General Convention, ubuntu, was chosen intentionally to focus on this. Often translated from its original African dialects as "I am because we are," ubuntu has significant biblical connections and warrant. The Hebrew prophets save their strongest denunciation for those who claim to be worshiping correctly but ignore injustice done to their neighbors (e.g., Amos 5:21-24), and Jesus insists that those who will enter the kingdom are the ones who have cared for neighbor by feeding, watering, clothing, housing, healing and visiting "the least of these" (Matt 25:31-46).
