The controversy: Whether person Q who is validly married to A, but having intercourse with B, may receive the Eucharist. Call this person QB.
Question: Are not all agreed that anyone who receives in the state of sin commits sacrilege? I think that all do agree on this. But I raise it as a question. I also premise it in what follows.
So, those who support QB receiving must be holding that he / she is in the state of grace. Let us pursue this. DOGMA: All those in the state of grace are able to fulfill the commandments of God. NOW: If QB may receive the Eucharist, he is in the state of grace. But if QB is in the state of grace, he is able to fulfill the commandments. Now, the commandment of fidelity in marriage is that one should not engage in intercourse with anyone other than one’s spouse. But QB is doing just that. Hence, he is doing what by God’s grace he is able Not to do, if that is, he is permitted to receive the Eucharist. That is, if he is in grace, he can quit B. Dilemma: If he cannot stop committing this objective sin, then it can only be that he is in a state of sin. All those in the state of grace are able to fulfill the commandments. By contrast, those in a state of sin are not necessarily guaranteed to have wherewithal to avoid every mortal sin (though they can avoid each). But if he is in a state of sin, he should not receive.
Another Oddity. The Bishops of certain nation have claimed that in the right circumstances QB may receive. What circumstances? If QB1 is unable to be faithful to the commandment and quit fornicating with B, but he would like to be faithful and quit B, then he may receive. Reason: QB does not have that much freedom. Conversely, if QB2 were able to quit B but doesn’t, then QB2 could not receive the Eucharist. This situation looks odd to me. Why? Because each of us is on a road to maturity. We are supposed to grow day by day. That growth should always take us nearer to the Eucharist. Now, if you fruitfully receive the Eucharist, you should be growing in freedom. Thus, if QB1 fruitfully received the Eucharist, he would be growing in freedom. Presumably, he would grow to the point at which he is able to quit B. At that point, if he quits B, great. If he does not quit B, he may no longer receive the Eucharist. Is it not odd that those with less moral freedom are permitted to receive?
Further oddity: If the goal of QB1 is to quit B, why are some praising QB1 precisely for engaging in intercourse with B, as though he is fulfilling the commandments of God thereby, doing what God is commanding?
In the midst of all this discussion back and forth, there are the countless poor souls who are losing sight of the real commandments and the real power of grace. For even those in the state of sin are objects of God’s love, which is presently calling them to ask him for the grace of conversion. But how can anyone seek grace who doesn’t think he needs it?
Another odd thing: Luther found sin everywhere. Too much sin in too many wrong places. He critiqued the presumptuous. And it is right to critique the presumptuous, those who deny that there is sin. But are we not in our age basically explaining away all sins? But if the sins are explained, they are not forgivable. Only the free evil is forgivable.
