Faith's Foundation

Οὐκ ἀγνοῶν τὴν τῶν ἀνθρώπων περὶ αὐτοῦ πολυώνυμον δόξαν ὁ τὰς καρδίας ἐμβατεύων Χριστὸς, ἥρετο τοὺς ἑαυτοῦ μαθητάς· Τίνα με λέγουσιν οἱ ἄνθρωποι εἴναι; ἀλλὰ τὴν ἀσπαλῇ ὁμολογίαν διδάξαι πάντας βουλόμενος, ἥν ἐμπνευσθεὶς ὁ Πέτρος παρ' αὐτοῦ ὡς κρηπῖα καὶ βάθρον ἀπέθετο, ἐφ' ᾗ τὴν ἕαυτοῦ Ἐκκλησίαν ὁ Κύριος ᾠκοδόμησε. Ἅγιος Ἰσίδωρος Του Πηλουσιώτου, Βιβλίον Πρῶτον, Ἐπιστολή ΣΛϚ',  Σερηνῳ

Christ, who sees into the heart, was not ignorant of the multitude of men's opinions, when He asked his disciples, 'Who do men say I am?' But wishing to teach all steadfast confession, it was by the inspired Peter he laid down a foundation and base on which He built his Church. Saint Isidore of Pelusium, Book 1, Letter 236, to Serenus
