Much of Thomas Aquinas' writing is dialectical in form. The emphasis on 'salvation by faith alone' came with Protestant fideism. — Wayfarer
Correct. I think Aquinas is a very good example of how Christianity faithfully preserved Plato’s core teachings for many centuries. Although some seek to argue that Christianity represents a distortion of Plato (as well as of Judaism), this is contradicted by the objective examination of historical facts.
As Lloyd Gerson has pointed out, if you were to ask any moderately well-educated person in antiquity what the goal of life is according to the teachings of Plato, they would answer “to become godlike as far as possible”.
Becoming a godlike immortal had long been a feature of Greek mythology which abounded in the offspring of Gods and mortals. Among these we find Hercules, himself the son of Zeus, who had joined the Gods in Olympus after death.
Among philosophers like Pythagoras, this became the goal or
telos of philosophical life. Plato and Socrates were merely prominent propagators of this tradition.
Thus Socrates says:
Therefore we ought to try to escape from earth to the dwelling of the Gods as quickly as we can; and to escape is to become like God, so far as this is possible; and to become like God is to become righteous and holy and wise (Theaetetus 176a – b).
That this was an actual Platonic teaching is suggested among other things by the fact that the desire to become godlike is found in King Phillip II of Macedon and his son Alexander the Great who had been instructed in philosophy by Plato’s pupil Aristotle. Phillip had already announced his wish to be treated as godlike or
isotheos. Alexander himself followed in his father’s steps and declared himself a God: following his conquest of Egypt, he adopted the pharaonic title of “Son of God Re” and became “Son of Zeus” to the Greeks.
Aristotle’s political theory that regarded the ideal king as a paternal ruler likened to Father Zeus, blended with the metaphysical theory of the philosophers and became part of Greek and later Roman culture.
By the time of Jesus, the political concept of the ruler as a deity as well as the philosophical goal of the deification of man was well-established. Unsurprisingly, the latter appears as a central teaching of the Christian Gospels:
“But as many as received him, to them gave he power to become the sons of God” (John 1:12).
“He called them gods, unto whom the word of God came” (John 10:35).
“The people who are right with God will shine like the sun in their Father's kingdom” (Matthew 13: 43).
“So try to be like God, because you are his own dear children” (Ephesians 5:1).
Christianity, especially in the east, preserved the political and administrative system of the Roman Empire and the emperor, though not a deity, remained a sacred representative of divine authority on earth. But Christianity also preserved Graeco-Roman culture with particular emphasis on the philosophy of Plato and Aristotle which represented the highest intellectual achievement of the classical era. Plato’s Academy at Athens continued to function till 529 CE and philosophy was taught at the Catechetical School of Alexandria and at the University of Constantinople (from 425 CE to 1453 CE).
The Platonic concept of deification or
theosis remained central to the teachings of the Greek Orthodox Church as can be seen from the writings of lead theologians and scholars like Maximos the Confessor (580 – 662 CE):
The soul’s salvation is the consummation of faith (cf. 1 Pet. 1:9). This consummation is the revelation of what has been believed. Revelation is the inexpressible interpenetration of the believer with the object of belief and takes place according to each believer’s degree of faith (cf. Rom. 12:6). Through that interpenetration the believer finally returns to his origin. This return is the fulfilment of desire. Fulfilment of desire is ever-active repose in the object of desire. Such repose is eternal uninterrupted enjoyment of this object. Enjoyment of this kind entails participation in supra-natural divine realities. This participation consists in the participant becoming like that in which he participates. Such likeness involves, so far as this is possible, an identity with respect to energy between the participant and that in which he participates by virtue of the likeness. This identity with respect to energy constitutes the deification of the saints. Deification, briefly, is the encompassing and fulfilment of all times and ages, and of all that exists in either. This encompassing and fulfilment is the union, in the person granted salvation, of his real authentic origin with his real authentic consummation. This union presupposes a transcending of all that by nature is essentially limited by an origin and a consummation. Such transcendence is effected by the almighty and more than powerful energy of god, acting in a direct and infinite manner in the person found worthy of this transcendence. The action of this divine energy bestows a more than ineffable pleasure and joy on him in whom the unutterable and unfathomable union with the divine is accomplished. This, in the nature of things, cannot be perceived, conceived or expressed.

What emerges from this is a process of faithful preservation of Platonic teachings rather than “distortion,” and Aquinas as a philosopher and theologian who accords great importance to the concept of deification, is a prime example and representative of this process.
If anything, the “distortion” is the work of Protestantism which has inspired and fuelled the anti-Platonist movement that emerged in the 1800’s and 1900’s.
By the way, Fraenkel sounds like an interesting author. “Philosophical Religion From Plato To Spinoza” would definitely be my kind of book. I think people tend to forget the close historical and intellectual links between religion and philosophy and regard them as mutually incompatible fields, which in my view is a mistake.
