Like turning wine and bread into flesh and blood, then eating it ?
Read John 6, and all of the Last Supper passages in the Gospels.
Like creating golden crosses, then kissing them ?
Your concern has turned up from time to time in the history of Christianity. From the perspective of the Catholic and Orthodox Churches, veneration of icons is an essential part of practicing religion. The Second Council of Nicaea states, "As the sacred and life-giving cross is everywhere set up as a symbol, so also should the images of Jesus Christ, the Virgin Mary, the holy angels, as well as those of the saints and other pious and holy men be embodied in the manufacture of sacred vessels, tapestries, vestments, etc., and exhibited on the walls of churches, in the homes, and in all conspicuous places, by the roadside and everywhere, to be revered by all who might see them. For the more they are contemplated, the more they move to fervent memory of their prototypes. Therefore, it is proper to accord to them a fervent and reverent adoration, not, however, the veritable worship which, according to our faith, belongs to the Divine Being alone — for the honor accorded to the image passes over to its prototype, and whoever adores the image adores in it the reality of what is there represented."
Like the superstitious belief in the water of Lourdes ?
Catholics aren't required to believe in anything associated with the apparitions of the Blessed Virgin Mary at Lourdes. The Church has verified only a few of the miracles that have taken place there. But the pious use of water from Lourdes is a demonstration of a person's faith in the healing power of God that has manifested itself through the springs at Lourdes, not in the water itself.
I'm pretty sure that a Muslim could come up with the same sort of explainations for their practices that Rev. J.L. Menezes is complaining about.
So I'm glad you illustrated the point.
