If the Christian church is to move responsibly towards the future, it must restore or renew its ties with its past. Contemporary Catholic and Protestant radicals want to claim that Christianity means whatever Christian today happen to believe and practice, be it pantheism, unitarianism, or sodomy. The Christian faith has suffered immeasurable harm because of the tendency of people to use the word Christian in a careless and non-historical way. Nothing in this argument would preclude liberal Protestants and Catholics from developing and practicing any religion they like.
