This is how today's piece begins:
On December 17 I addressed the question of whether Muslims and Christians worship the same God. I gave the by Vatican II, and by the
Catholic Church since the Council: yes. Muslims and Christians do worship the same God, even though Islam holds an imperfect understanding of the divine, since it denies Christ’s divinity and thus, by implication, God’s triune nature.
As the Church declared in Nostra Aetate (1965): “[Muslims] adore the one God, living and subsisting in Himself; merciful and all- powerful, the Creator of heaven and earth, who has spoken to men. . . .Though they do not acknowledge Jesus as God, they revere Him as a prophet.”
This argument prompted several critical replies, almost exclusively from non-Catholic Christians, including distinguished thinkers such as Albert Mohler, Andrew Walker, Matthew Cochran, and Peter Leithart. (To say nothing of a raft of outrage from TCT readers.) Each, with differing emphases, correctly documents what Christians believe are the inadequacies of Muslim theology given how God has progressively revealed himself through history as taught in Scripture. I do not dispute this point; it is actually consistent with my argument. Let me explain.
The Church’s view rests on the distinction between “general” and “special” revelation. The former concerns those truths about God that can be known through unaided human reason; the latter, those truths about God known only through Scripture, Sacred Tradition, and/or the Holy Spirit speaking through the magisterium. (Many Protestants also accept this distinction, though they only include Scripture under the category of special revelation).
In order to better grasp this distinction, let’s consider an argument for the existence of a Creator God offered by the Persian Muslim philosopher, Al-Ghazali (1058-1111 AD): the “Kalam Cosmological Argument.” It figures prominently in the work of Evangelical philosopher and apologist William Lane Craig. He summarizes the argument in this way:
