On one of the Catholic news sites out there, I was involved in a debate with another reader about the issue of divorce and remarriage. This individual argued that the Church, in confirming that remarriage after divorce (as opposed to receiving an annulment first) is morally wrong, was ignoring the words of Our Lord concerning the parable of the lost sheep. In other words, this individual was asserting that to show mercy to the divorced and remarried, the Church had to stop teaching their actions were sinful and needed to admit them to Communion.
This kind of thinking confuses mercy with tolerating a lack of restraint, and misses the point of what mercy is. It seeks to assuage the conscience of the sinner by telling him or her that their actions are not even sins at all. The Church is accused of being merciless because she will not change herself when people demand that she stop saying things are sins. The reason she will not is because she cannot contradict God’s commands without being faithless to God. When God commands that we do X or avoid Y, the Church cannot permit us to avoid doing X or permit us to do Y. As Our Lord said, “If you love me, you will keep my commandments” (John 14:15).
