The saying is sure and worthy of full acceptance, that Christ Jesus came into the world to save sinners. In the New York Times recently there was a full page ad for Columbia University. Nervousness is caused by the awareness that there are an awful lot of people who really believe in Christianity. Even in religious studies departments, faculty members who are Hindus, Buddhists, and believers in Mystical Crystals can quite openly profess their faith. Muslims and, usually, Jews can, too.
Nobody raises a question about their proselytizing.
Not so with Christians. The fear is that Christianity might be taken altogether too seriously. The absence of Christian Studies in the Columbia program, it turns out, is not an insult to Christianity. Those of the other faiths, however might have reason to be offended. I think he is right.
