"To put it as simply as possible: I am not a Muslim.[...] I do not accept the charge of apostacy, because I have never in my adult life affirmed any belief, and what one has not affirmed one can not be said to have apostasized from. The Islam I know states clearly that 'there can be no coercion in matters of religion'. The many Muslims I respect would be horrified by the idea that they belong to their faith purely by virtue of birth, and that a person who freely chose not to be a Muslim could therefore be put to death."

Contemporary Christianity, diverse and complex as we find it, actually may show more unanimity than the Christian churches of the first and second centuries. For nearly all Christians since that time, Catholics, Protestants, or Orthodox, have shared three basic premises. First, they accept the canon of the New Testament; second, they confess the apostolic creed; and third, they affirm specific forms of church institution. But every one of these - the canon of Scripture, the creed, and the institutional structure - emerged in its present form only toward the end of the second century.
