Εἰ ἐλαττώτεως τοῦ Υιοῦ τοῦ Θεοῦ συμεῖον νομίζουσιν οἱ κακόσχολοι, τὸ τῷ εὐαγγελιστῇ περὶ αὐτοῦ εἰρημένον, Δόξαν ὡς Μονογενοῦς παρὰ Πατρὸς, ἐλαττοῦσθαι καὶ τὸν Θεὸν εἰς ἀγαθότητα, νομιζέτωσαν, τοῦ Δαβὶδ λέγοντος, Ὡς ἀγαθὸς τῷ Ἰσραὴλ ὁ Θεός; Εἰ δὲ ἐνταῦθα κατὰ ἐπιτασιν τὸ, Ὡς ἀγαθὸς, εἴρηται, κἀκεῗσε τὸ, ὡς Μονογενοῦς, κατὰ βεβαίνωσιν καὶ ὁμοίωσιν γέγραπται. Ἅγιος Ἰσίδωρος Του Πηλουσιώτου, Βιβλιον Πρῶτον, Ἐπιστολή ΥΟΓ´ Παλλαδιῳ Διακονῳ Source: Migne PG 78.441a

If men who spend their leisure poorly think it is a sign that the Son of God is diminished because the Evangelist said: 'Glory as the Only Begotten of the Father,' 1 they also judge the benevolence of God is diminished when David uses the words: 'So good is God to Israel.' 2 Because if in this place these words, 'So good', were spoken for amplification, so there also the words, 'as the Only Begotten', were written for confirmation and likeness. Saint Isidore of Pelusium, Book 1, Letter 473, to Palladius the Deacon 1 Jn 1.14 2 Ps 72.1
