Why do Catholics genuflect?
Catholics genuflect because we are often in the presence of the Supreme Revelation, who is not a piece of data but a glorious Person. “Jesus Christ is the redeemer of the human race and is the center of human history and the cosmos,” as Pope John Paul II writes in the beginning of his first encyclical. Socrates asked, What is truth? Buddha taught the Four Noble Truths. Mohammed claimed to bear witness to the truth. But only Jesus of Nazareth dared to say, “I am…the truth” (John 14:6).
