Among other things, Cardinal Ratzinger said:
How many winds of doctrine have we known over the last few decades! How many ideological currents! How many schools of thought! The little ship bearing the thoughts of many Christians has frequently been shaken by these waves, thrown from one extreme to the other: from Marxism to liberalism, even to libertarianism; from collectivism to radical individualism; from atheism to a vague religious mysticism; from agnosticism to syncretism, and so on. Every day new sects arise, and St. Paul's words concerning the deception of men and the cunning that leads into error come true. Having a clear faith, according to the Creed of the Church, is often labeled as fundamentalism. While relativism, in other words allowing oneself to be 'tossed to and fro with every wind of doctrine,' appears as the only attitude appropriate to modern times, a dictatorship of relativism is being formed, one that recognizes nothing as definitive and that has as its measure only the self and its desires.
