One of the most dramatic examples of this is an encyclical written by Pope John Paul II, entitled Veritatis Splendor ("The Splendor of Truth.") In it, the pope wrote that the morality of an act has nothing to do with its result, its social context, its circumstance, its intent, or the process by which a person's conscience comes to his decision. The act is simply right or wrong, in and of itself, and it will always be that way, no matter what the surrounding considerations. Furthermore, the rightness or wrongness of an act is revealed to us by God, through the highest authorities of the church. They cannot be questioned. Humans are not supposed to wrestle with moral dilemmas, but to apply these revealed truths to every situation and problem in life.
The most obvious result of putting this belief into practice is that it gives supreme power to the highest leaders of the Church. It is no wonder that religious leaders find moral absolutism so attractive, and are so insistent upon everyone putting it into practice. Conservatives may object that the power actually belongs to God, and the church leadership is simply transmitting the information. But history clearly refutes this idea. African slavery in America received the full blessing of four centuries of popes. Considering the social and scientific disasters that the Church hierarchy (of all denominations) have been guilty of promoting, from the burning of witches to the enslavement of innocents, no thinking person could ever place blind faith in the fallible leadership of men.
That's just a practical observation; let's turn to a more theoretical treatment of moral absolutism. The problem with this theory is that not even the Bible considers an act to be wrong in and of itself. God gave Israel the Ten Commandments forbidding certain acts, but then he also ordered Israel to carry out those very acts against her enemies. This sort of moral relativism is apparent in Christian history as well. Slavery and war were not condemned as evil in and of themselves; Christian scholars and popes wrote entire libraries on what constituted "just and unjust slavery" and "just and unjust war." They drew all the exceptions permissible under God for these atrocities, which they viewed as correct in certain circumstances. They also did this with more positive behaviors, such as the only correct occasions to have sex, which the Church otherwise viewed as a great evil. The argument that morals are absolute, then, despite their context, is completely inconsistent with Christian history and practice.
The most a conservative can argue is that the law is relative, but it is up to God to decide where to permit the exceptions. Christians should then follow his exceptions as moral absolutes. This is a bit like the old-school physicist, who, upon learning that Einstein had proven that the universe is relative, proclaimed, "But this relativity is nonetheless absolute!"
