As the spirit of the age proclaims a new freedom from the traditional sexual ethic, discussion about marriage in the church today runs the risk of becoming bogged down in what are in one sense peripheral issues. Marriage is seen as an institutionalisation of eros, as the expression of a sexual ethic, and the question of any specifically Christian meaning of marriage is lost in ethical discussion.
This is not to imply that the ethical dimension is unimportant; but it is not the only dimension to be considered. The revolt against the late medieval and modern tradition, with its attendant rigidity, should not be allowed to obscure the search for a theology of marriage as a sign of the Kingdom, as a sacrament.
This has been tied to a hard line on the question of divorce and remarriage, to a doctrine of indissolubility that has been seriously questioned in recent years. Even more common perhaps is a pastoral praxis that, while freeing people from the more oppressive features of the old ideology, may also reduce the discussion of marriage as a sacrament to the status of a non-question. In justice it should be pointed out that the defence of an absolute indissolubility has been driven back to the question of sacramentality. In the practice of the modem church, as expressed in the Roman Curia, non-sacramental marriages are not indissoluble. Nor in fact are all sacramental ones; the maze of technicalities involved in this practice often defies the comprehension of the layman.
Consideration of marriage as a sacrament often appears indissolubly linked to this world of the canonists, to a legal structure that is more easily bypassed than challenged. At the same time, questions of sexual ethics retain their relevance against the background of the new praxis as they did against that of the old.
