Pope John Paul II said the following regarding Muslims:
“Continuing our discussion of inter-religious dialogue, today we will reflect on dialogue with Muslims, who "together with us adore the one, merciful God" (Lumen gentium, n. 16; cf. CCC, n. 841). The Church has a high regard for them, convinced that their faith in the transcendent God contributes to building a new human family based on the highest aspirations of the human heart….
We Christians joyfully recognize the religious values we have in common with Islam. Today I would like to repeat what I said to young Muslims some years ago in Casablanca: "We believe in the same God, the one God, the living God, the God who created the world and brings his creatures to their perfection"
One of the Catholic commenters on my post about the One True Church of Allah said:
“According to the Qu'ran. Allah is the God of Abraham, Issaac and Joseph.”
If the Catholic position is correct, that the Catholics and Muslims worship the same God, then it seems to me that the Roman Catholic Church is missing a large portion of their canon – the Qu’ran. Since Muslims believe that the Qu’ran is God’s revealed word and the Catholics believe in the same God, then the Roman Catholic Church needs to encompass this divine revelation as it’s own to be consistent.
If the Roman Catholic Church does not believe the Qu’ran is the inspired Word of God, then the Church is mistaken in its belief that the Muslims worship the God of Abraham since the source of that proclamation comes from the Qu’ran. It is inconsistent to state that Catholics and Muslims share the same one true God but dismiss the divine, written revelation made to the Muslims.
One has to wonder how a supposedly infallible organization could make such a blunder.
