Objection: The record of Christians.
Every religion will have its hypocrites of course. But it seems that the most fervent Christians are the most condemning, exclusive, and intolerant. The church has a history of supporting injustices, of destroying culture, of oppression. And there are so many people who are not Christian (or not religious at all) who appear to be much more kind, caring, and indeed moral than so many Christians. If Christianity is the true religion — then why can this be? Why would so much oppression have been carried out over the centuries in the name of Christ and with the support of the church?
Response: The solution to injustices is not less but deeper Christianity. 1) There have been terrible abuses. 2) But in the prophets and the gospels we are given tools for a devastating critique of moralistic religion. Scholars have shown that Marx and Nietzsche’s critique of religion relied on the ideas of the prophets. So despite its abuses, Christianity provides perhaps greater tools than the other religions do for its own critique. 3) When Martin Luther King, Jr. confronted terrible abuses by the white church he did not call them to loosen their Christian commitments. He used the Bible’s provision for church self-critique and called them to truer, firmer, deeper Christianity.
