Both Karl Barth and John Paul II have written extensively on marriage and procreation. Coming from different traditions, they have of course different things to say. The aim of this paper is to show that the differences between them highlight theologically important questions relating to the symbolism of marriage, the value of procreation and the parental mission. Both theologians share the view that as Christians we must see the world and human relationships in the light of the Gospel News, and so from an eschatological perspective. Both of them, therefore, hold that under the New Covenant in Christ the relationship between mankind and God and also between man and woman in marriage take on a new meaning. But, nevertheless, they differ on the importance of procreation and also on the question of the God-given parental mission. The exploration of these differences will bring to the fore the question of what moral obligations are entailed by the concept of the child as a gift, a concept espoused by both theologians. It will also bring to the fore the question of the basis of the fourth commandment.
The paper starts with a comparison between the two theologians’ views on marriage and procreation. Here it is shown why Barth considers procreation relativised under the New Covenant in Christ and so why he attaches less importance to procreation than John Paul II does. In the second part of the paper the two theologians’ views on the main role and mission of parents are discussed and it is shown why John Paul II puts the emphasis on the evangelising role of parents as Christian educators, whereas Barth stresses the symbolical role of parents as representatives of God.
