At the start of a new century it is clear that the Christian church and the growing and influential evangelical movement within it will face many challenges in the realm of moral theology. New issues will certainly arise which demand fresh serious thought and do not fit easily into traditional categories but it also likely that there will be calls for revision of the church’s traditional ethical teaching in numerous areas. At one level this is nothing new. The church has constantly had to address new concerns and respond to changing culture. In the last half-century it faced the challenges of the sexual and technological revolutions in western society and how faithful disciples of Christ should respond to these will remain areas of controversy for many years to come.
