The idea of establishing a permanent Catholic-Muslim forum is not without merit for the two faiths are committed to the postulate of revelation remaining transcendent as well as immanent. This commitment, however, cannot permit the de jure flux of endless interpretations and re-interpretations of what constitutes the transcendent and symbolic order. The distinction between the primary and secondary orders of meaning mitigates against the tendency to want to substitute the divine, allegorical or anagogical symbolism of the two faiths with unending secondary and tertiary commentaries of one kind or another. In order to arrest the seemingly harmless flow of such discourse, the idea of orthodox eternity -one that is vouchsaved and preserved through the integral purity of the symbol - is of paramount importance. Interpretative tertiary commentaries and revision, though of quite limited usefulness, in fact mark a kind of decline from the order of meaning for which the symbol is the exclusive providential guarantor. Everything has its limits and in the realm of genuine mutual inter-faith dialogue prolixity is not always an advantage. If the cosmologies of the two faiths speak to our highest faculties and capacities they do so not merely by reflection on the divine nature of the world but equally on the proleptic intelligibility of God. The apparent incompatibility between the prerequisites of liberation through knowledge, so characteristic of Islam and the salvation of Grace so characteristic of Catholicism and Orthodoxy, cannot be held ransom to any beguiling false alternativism: God can be known both with the theomorphic intellect - our "deepest self" and through the personal aspects of his Grace. A permanent Inter-Faith Forum at the Vatican cannot but mirror itself on the celestial model of Divine redemption through these two compatible paths. The recent visit of His Majesty King Abdullah of Saudi Arabia to the Vatican marks a historic stage in the intellectual absorption of two spheres now bound by the intimate nature of our interrelated world.
