But consider some points: all Christians together celebrate with pride the great accomplishments of Christians from other groups: Handel is not celebrated by Lutherans alone, Mozart has more than a Roman Catholic audience, Dostoevsky is lauded by many Christians who have never set foot in an Eastern Orthodox church.
Consider some more points: all Christians together hang their heads in shame with the dishonor of those in other camps, whether the issue is a pedophile priest or a televangelist calling for the assassination of a foreign leader.
If one part suffers, all the parts suffer with it; if one member is honored, all the members rejoice with it. (1Co 12:26)Sounds like us, doesn't it? We may disown each other when we embarrass each other, but that doesn't change that we still belong to each other. I mean, we don't get embarrassed when Mormons do something goofy like bribe Olympic officials, do we? So as Paul was saying, the greatest thing we should strive for is love.
