You have never seen an idol in a Catholic Church. An image is an idol only when it is the object of divine worship. You have seen images in Catholic Churches, but every Catholic knows that divine worship cannot be offered to such images. Would you call the Statue of Liberty, in New York harbor, an idol? As for your not seeing sincere Christians in a Catholic Church, you cannot expect to test the sincerity of a Christian by the color of his tie or the shape of his shoes.
