Conditions for validity
The similarities of these two types of personal communions are likewise helpful in reaching conclusions about the conditions for a truly valid encounter in the marital communion. For the worthy reception of the Eucharist, for a Holy Communion, the communicant at the minimum must be free from mortal sin. And what does this mean? It means that he must not be set against the covenant, that he must not be opposed to any sacrifice that might be demanded from him in order to remain true to his covenant with his Savior. For the communion of sexual intercourse to be a means of holiness or, at the least, not a means of unholiness, the spouses must likewise be free from any obstacles that will deny the covenant that they have made before God. If they have taken each other for better or for worse, their renewal of their marriage covenant must likewise be for better or for worse. Just as when they pledged to give themselves and to receive the other regardless of the consequences, so also must their subsequent communion in the marriage act be free from any denial of this covenant.
In the reception of the Holy Eucharist, it is not enough to be “generally” turned toward God. A person in a state of sin may not look back to last year (when faced with fewer temptations he was not in a state of sin) and receive the Eucharist on the basis of last year’s state. His present state is all-important. Nor may he look forward to the unknown future and, under an intention to leave the state of sin sometime in the future when conditions are less pressing, receive the Eucharist in his present state of sin. The worthiness of his Communion depends upon his present state of soul, his present willingness to give of himself in following Christ. In other words, he may not play a percentage morality and state that since most of the time he is open to the sacrifice required by Christian life, he may therefore worthily receive Communion at any time even though he be temporarily alienated from God and unwilling to live the life of love as his circumstances demand it. What he must avoid in this particular example is the false application of what might be called a principle of totality.
One of the current [mid-1960s] questions concerning marriage and sexual intercourse is whether it is not sufficient to have the marriage as a whole open to the service of life but permissible to exclude positively that openness to life in the expression of mutual love in sexual intercourse. It renews again the conflict between the purposes of marriage—procreation and mutual development. Or to state it positively, would it not be permissible to positively preclude the possibility of conception through direct contraception? According to some, a principle of totality, under which the marriage as a whole is open and generous in the service of life, would be sufficient; but it would not be necessary for each and every act of married sexual love to reflect that openness even in a minimal way, i.e., at least open to the remote possibility though not intending procreation.1
Personally, I find the approach very attractive, especially when I imagine some family burdened by a severe health problem on the part of the woman which makes pregnancy extremely dangerous, and whose openness to the service of life is witnessed by the adoption of other children. Because of these hardships, it is all the more important that the question be clearly answered: Is marriage itself and the overall generosity and openness to life the only sacred reality involved, or is the act of married sexual intercourse something sacred of itself—something whose sacred character must be respected in every instance regardless of circumstances? Or to put the question in terms of today’s ethical theories, is the sacred character of the married sexual act something absolute or is it conditioned by the situation of the married couple?
