If you know anything about Pseudo-Dionysius you will know that his works, aside from the Bible, were the most studied works of the Medieval period. Though certain works of Augustine were just as influential, Augustine’s complete works did not become available until the 14th century. Even Aquinas, known for his devotion to Aristotle and Augustine refers to Pseudo-Dionysius more than any other author in his opera. Among Protestants, Dionysius never carried as much authority as with other Christian traditions, primarily because Valla’s proof of forgery was unanimously accepted by all of the Reformers. Also, Luther’s and Calvin’s criticisms of “that Dionysius whoever he was” mentioned the latter’s seemingly unbridled devotion to Platonic philosophy, placing him at odds with their renewal of biblical exegesis.
Modern research on the Corpus Dionysiacum, however, through the use of modern tools of textual criticism has displayed a more careful reading of the Pseudo-Areopagite. My point here is not to summarize the entirety of this research but to point out the curious mixture of biblical and Proclian exegesis within Dionysius’s works. István Perczel, for instance, makes an interesting point re: Dionysius’s eclectic synthesis:
It is quite obvious that the structure of the Dionysian Corpus imitates that of the New Testament. We have in Dionysius three « synoptic Gospels », so to speak: the Divine Names and the two Hierarchies; another « Gospel », the Mystical Theology which, like Saint John, treats the loftiest theological ideas, and, finally, letters clarifying the meaning of the « Gospels. » And just as the canonical Gospels tell the same story – that of Jesus the Son of God – from different aspects, so the four major treatises of Dionysius treat one common story – that of the manifestation of the divine in the world – from four different angles. In this context, it is all the more interesting to note that the structure of all four treatises is determined above all by the Platonic Theology of Proclus. Perczel, “Pseudo-Dionysius and the Platonic Theology,” in Proclus et la Theologie Platonicienne: Actes du Colloque International de Louvain (13-16 mai 1998), A. Ph. Segonds and C. Steel, eds., (Leuven University Press, 2000), 491-531.
Based on this information, one may interpret the Dionysian enterprise as an attempt at Neoplatonic biblical exegesis similar in some ways to that of Augustine.
