From the earliest days of the Christian faith, Christians have honored holy matrimony (as Christian marriages are referred to) as a divinely blessed, lifelong, monogamous union, between a man and a woman. According to the Episcopal Book of Common Prayer (1979), reflecting the traditional view, "Christian marriage is a solemn and public covenant between a man and a woman in the presence of God," "intended by God for their mutual joy; for the help and comfort given one another in prosperity and adversity; and, when it is God's will, for the procreation of children and their nurture." However, while many Christians might agree with the traditional definition, the terminology and theological views of marriage have varied through time in different countries, and among Christian denominations.
