There is no doubt that Peter Sterry (†1672) was both a Puritan and a Platonist. He was a devotee of Jesus and Plato, but only insofar as the latter agreed with and prepared one for the teachings of (and union with) the former. In a letter that he wrote to his son Peter (junior), Sterry combines the myth of the soul’s journey to absolute Beauty in the Phaedrus with the Christian doctrine of faith as a quasi-intellectual vision of Jesus within the soul in order to encourage his son to turn from his devotion to earthly passions and turn to Jesus. In this regard, Sterry appears as Socrates guiding his son to Beauty in Jesus by means of his influence and letters.
Your letters have both pleased mee well. I waite with hope to see with Joy that Eternall spirit, which is the seede of the Divine nature in you to carry on its owne Buds, and Blossomes to ripe Fruite. With all your Might thorrow the power of the glory of Christ in you, Follow after integrity, spirituality, constancy. Can hee that sees the Beauty of Christ’s face unveiled in him, and feeles Divine Love springign up imediately from its own Fountayne in his Soule, think, speake, or act from any other Principle, than the Light of this beauty, the Life of this Love, or to any end, besides the enlargement, and Propogation of the power, purity, Joyes, of this heavenly Light, and Life? O my Son, what sweeteness, Lovelynes, Strenth is there in being established in this grace, as a Tree in its Roote, in moving directly, continually towards this glory, without Gaps, or interruptions, as rivers to the Sea […] Hath the Life of Christ all things of heaven, and Earth in itself, as so many lives of Immortall Beauty, as so many Fountaynes of purest pleasures; have you by the good will of the everlasting Father thorrow that Essentiall Word his Son, this Life begottne in you, and can you doe any thing but abide in the actings of this Life, feede it, forme it in the Soules of others? So live in Christ, and Christ in you… (Peter Sterry, Selected Writings, ed. N.I. Matar. Peter Lang: 1994. pp. 133, 134)
