Pure of Heart: From Ancient Rites to Renaissance Plato

The philosopher who published Plato for Western thought praised him strangely. Marsilio Ficino commended his translation of the Phaedrus to his soul mate Iohannes Bessarion because in that dialogue Plato sought from God spiritual beauty. "When this gold was given to Plato by God, it shone in him most brilliantly, because he was so pure in heart." The epithet "pure in heart" is not literally Ficino's diction: he wrote "in his Platonic bosom perfectly clean" (Platonico in sinu utpote mundissimo). ¹ Although this philological variant insinuates his full meaning, the modern translation conveys his essential import. Ficino and Bessarion were both scholars and priests, convinced of the compatibility of Platonism with Christianity. The recipient of the letter, Bessarion, had defended the Phaedrusvigorously against protestations that, for promoting the criminal activity of pederasty, it was an obscene work of unchaste philosophy. "Love," he declared, "leads many to beatitude." ² Ficino emphasized that "no one can attain beatitude, which consists in divine contemplation, unless he loves God ardently." ³ To that end he translated the complete works of Plato into Latin with commentaries. He also composed a speculative Theologia platonica. The pair would have approved of the application to Plato of the gospel promise "Blessed are the pure of heart [hoi katharoi t¯e kardia], for they shall see God" (Matt. 5:8). Was this promise not already fulfilled in Plato, even before Jesus' pronouncement? Did not Socrates in the Phaedrus soar to the vision of God in his myth of the charioteer, where among privileged souls he peered over the rim of intelligible being to behold the divine processional and true being? The myth figured the recollection of the soul's primordial state of innocence, "when we were pure ourselves," and, beholding "the beatific vision," were initiated into its "most blessed" mystery. ⁴ Bessarion cited the passage defensively, declaring Socrates' speech "most holy." ⁵

The beatitudes, from which "pure of heart" derived, emphatically comprised the opening discourse of Jesus' Sermon on the Mount. Jesus blessed the poor in spirit, the mourners, the meek, those hungry and thirsty for righteousness, the merciful, the pure of heart, the peacemakers, and those persecuted for righteousness. He pronounced a corresponding good for each type (Matt. 5:1-10). The first four beatitudes promised reversals for the unfortunate; the second four, eschatological rewards for the virtuous. ⁶ Ficino personalized the beatitudes. He applied them in a letter to an archbishop to his own contrasting status as a priest "of humble fortune." Indicating his slight financial means, he affirmed obedience to his lot, even contentment with his meager possessions. He then wielded the divine reversal of human judgment, so startling in the beatitudes, against his enemies. "I am certainly content with few possessions, even though I am often held in contempt by many; for these many ought to be deemed of little worth. Blessed are the poor in spirit. Blessed are the peacemakers." ⁷

Ficino also philosophized the beatitudes. He argued in Theologia platonica that, although the celestial realm was usually considered fiery, it could be earthy, as poets imagined the Elysian Fields. Jesus' beatitude promising the possession of the earth to the meek was proof. Ficino expounded the nine grades of celestial beatitude as a belief shared by Platonists and Christians. He assigned these grades to varying degrees and combinations of three ends: the fear of divine power, the search for wisdom, and the love of good, which ultimately transformed the soul. This elaborate division Ficino compared to Jesus' beatitudes. "I think that this mystery is signified in the gospel, where the divine oracle nine times calls his disciples blessed, because through nine grades of merit, with God leading, the nine heavens are sought blessedly through nine degrees of contemplation." Despite his philosophical imposition on the biblical text, Ficino qualified his syncretism. The gospel admonished the dismissal of philosophical meanderings to pursue...
