To state, as the Council did in Lumen Gentium n. 16, that Muslims adore together with us the one God (“nobiscum Deum adorant”), is theologically a highly ambiguous affirmation. That we Catholics adore with the Muslims the one God is not true. We don’t adore with them… Islam rejects the Holy Trinity. When the Muslims adore, they do not adore on the supernatural level of faith. So even our act of adoration is radically different… Precisely because we turn to God and adore Him …, and we do this with supernatural faith. However, the Muslims do not have supernatural faith. I repeat: they have a natural knowledge of God. The Koran is not the revelation of God, but a kind of anti-revelation of God, because the Koran expressly denies the divine revelation of the Incarnation, of the eternal divinity of the Son of God, of the redemptive sacrifice of Christ on the Cross, and therefore denies the truth of God, the Holy Trinity.
This ambiguous affirmation of the Second Vatican Council must be corrected. This affirmation is not infallible and was not meant by the Council to be such. In some way, we can accept the affirmation of Lumen Gentium, but then we must give a long explanation. Of course, when a person sincerely adores God the Creator—as I assume the majority of simple Muslim people do—they adore God with a natural act of worship, based on the natural knowledge of God, the Creator. Every non-Christian, every non-baptized person, including a Muslim, can adore God on the level of the natural knowledge of the existence of God. They adore in a natural act of adoration the same God, whom we adore in a supernatural act and with supernatural faith in the Holy Trinity. … The affirmation of the Second Vatican Council should have been written more precisely, in order to avoid misunderstandings. …[if rewritten precisely] it would have avoided wrong applications in interreligious dialogue and wrong teachings in so many theological faculties and priestly seminaries in our days.
