Multiculturalism, which is so passionately promoted, can sometimes amount to an abandonment and denial, a flight from one’s own things. Multiculturalism teaches us to approach the sacred things of others with respect, but we can do this only if we ourselves are not estranged from the sacred, from God. With regard to others, it is our duty to cultivate within ourselves respect for the sacred and to show the face of the revealed God—the God who has compassion for the poor and the weak, for widows and orphans, for the foreigner; the God who is so human that he himself became man, a man who suffered, and who by his suffering with us gave dignity and hope to our pain.
Unless we embrace our own heritage of the sacred, we will not only deny the identity of Europe. We will also fail in providing a service to others to which they are entitled. To the other cultures of the world, there is something deeply alien about the absolute secularism that is developing in the West. They are convinced that a world without God has no future. Multiculturalism itself thus demands that we return once again to ourselves.
