87 To what extent should the Church adapt itself to the historical and local circumstances in which it has to exercise its mission? How is it to guard against the danger of relativism which would make it untrue to its own dogmas and moral principles? And yet how can it fit itself to approach all men and bring salvation to all, becoming on the example of the Apostle Paul "all things to all men," that all may be saved? (58)
