Trinity (Koranic): The Trinity “Father, Son, and Mother”, which the Koran   attributes to Christianity, has three meanings: first, it expresses a psychological situation de facto, Mary being much more present to Christian people, so far as a truly divine function is concerned, than is the Holy Ghost; second, it implies that the Holy Virgin is identified with the Spirit insofar as she is the Wisdom that has been “set up from everlasting, from the beginning, or ever the earth was” (Proverbs 8:23); third, the Koranic formulation has to stress the exoteric incompatibility of Christian Trinitarianism with Islamic Unitarianism.

Trinity (metacosmic, macrocosmic, microcosmic): The “Father” is God as such, that is as metacosm; the “Son” is God insofar as He manifests Himself in the world, hence in the macrocosm; and the “Holy Spirit” is God insofar as He manifests Himself in the soul, hence in the microcosm. From another point of view, the macrocosm itself is the “Son”, and the microcosm itself – in its primordial perfection – is identified with the “Holy Spirit”; Jesus corresponds to the macrocosm, to the entire creation as divine manifestation, and Mary corresponds to the “pneumatic” microcosm; and let us recall in this respect the equation that has been made sometimes between the Holy Spirit and the Divine Virgin, an equation that is linked, in some ancient texts, to the feminization of the Divine Pneuma.

Trinity (“vertical” and “horizontal”): The Trinity can be envisaged according to a “vertical” perspective or according to either of two “horizontal” perspectives, one of them being supreme and the other not. The vertical perspective – Beyond-Being, Being, Existence – envisages the hypostases as “descending” from Unity or from the Absolute – or from the Essence it could be said – which means that it envisages the degrees of Reality. The supreme horizontal perspective corresponds to the Vedantic triad Sat (supraontological Reality), Chit (Absolute Consciousness) and Ananda (Infinite Beatitude), which means that it envisages the Trinity inasmuch as it is hidden in Unity.* The non-supreme horizontal perspective on the contrary situates Unity as an Essence hidden within the Trinity, which is then ontological and represents the three fundamental aspects or modes of Pure Being, whence the triad: Being, Wisdom, Will (Father, Son, Spirit). (* The Absolute is not the Absolute inasmuch as it contains aspects, but inasmuch as it transcends them; inasmuch as it is Trinity it is therefore not Absolute.) [GTUFS: UIslam, The Quran]
