"The fact that the Catholic Church is singled out by Fundamentalists as the Whore reveals that they intuit the fact it has an important role in God’s plan. No other church gets accused of being the Whore—only the Catholic Church. And it is understandable why: The Catholic Church is the largest Christian body, larger than all other Christian bodies put together, suggesting a prominent place in God’s plan. Fundamentalists assume, without objectively looking at the evidence, that the Catholic Church cannot be the Bride of Christ, so it must be the Whore of Babylon.
Yet the evidence for its true role is plain. The First Vatican Council taught that "the Church itself . . . because of its marvelous propagation, its exceptional holiness, and inexhaustible fruitfulness in all good works; because of its Catholic unity and invincible stability, is a very great and perpetual motive of credibility and an incontestable witness of its own divine mission" (On the Catholic Faith 3).
So why is the Bride maligned as the Whore? Jesus himself answered the question: "If they have called the master of the house Beelzebul, how much more will they malign those of his household" (Matt. 10:25). "If the world hates you, know that it has hated me before it hated you. If you were of the world, the world would love its own; but because you are not of the world . . . the world hates you. Remember the word that I said to you, ‘A servant is not greater than his master.’ If they persecuted me, they will persecute you" (John 15:18–20)."
