Christian bioethics springs from the worship that is the response of the Church to the Gospel of Jesus Christ. Such worship is distinctively political in nature, in that it acknowledges Christ as Lord. Because it is a political worship, it can recognize no other lords and no other prior claims on its allegiance: these include the claims of an allegedly universal ethics and politics determined from outside the Church. However the Church is called not just to be a contrast society, (...) but also to witness to the freeing of the world from salvific pretensions in order that it may embrace its proper temporality. The implications of this for the distinctiveness of Christian bioethics are brought out in three movements: first, the Church's itself learning how it is to conceive bioethics; second, the Church's role in unmasking the idols of secular bioethics; and third, the Church's witnessing to the freeing of medicine from idolatrous aspirations.
