It is a philosophical term which means that there is no objective truth that exists independently of human subjectivity or thinking. It means that there is no objective common ground that all can know and agree on. According to this philosophy, one does not know the truth, rather one wills the truth or even feels it, so it is individual and subjective. One consequence of this view is that each person creates his own truth, goodness and values-each person creates his own reality. According to this view, circumstances and intention can turn such things into good acts.
Relativism is a problem for the faith today because it puts all religions on the same level.
Thus, it denies the divinity of Jesus Christ and puts him on the same level as any other religious leader, such as Buddha or Mohammed. They are considered dangerous and a threat to the supreme good of modernity, namely, tolerance and freedom. But since relativists have a false view of man, they also have a false view of freedom. Since Vatican II we have heard a lot about dialogue. It has been assumed that if opposing parties just sit down and talk together long enough they can reach consensus.
