Being Peter

Εἰ δὲ φήσαντες καὶ ἡμεῖς, ὡς ὁ Πέτρος· Σὺ εἴ ὁ Χριστὸς ὁ Υἱὸς τοῦ Θεοῦ ζῶντες, οὐχ ὡς σαρκὸς καὶ αἰματος ἡμῖν ἀποκαλυψάντων, ἀλλὰ φωτὸς ἡμῶν τῇ καρδίᾳ ἐλλάμψαντος ἀπὸ τοῦ ἐν οὐρανοῖς Πατρὸς, γινόμεθα Πέτρος· καὶ ἡμῖν ἂν λέγοιτο ἀπὸ τοῦ Λόγου τό· Σὺ εἴ Πέτρος, καὶ τὰ εξῆς. Πέτρα γὰρ πᾶς  ὁ Χριστοῦ μαθητὴς, ἀφ' οὗ ἔπινον οἱ ἐκ πνευματικῆς ἀκολουθούσης πέτρας, καὶ ἐπὶ πᾶσαν τὴν τοιαύτην πέτραν οἰκοδομεῐται ὁ ἐκκλησιαστικὸς πᾶς λόγος, καὶ ἡ κατ' αὐτὸν πολιτεία· ἐν ἐκαστῳ γὰρ τῶν τελείων ἐχόντων τὸ ἄθροισμα τῶν συμπληρούντων τὴν μακαριότητα λόγων, καὶ ἔργων, καὶ νοημάτων, ἔστιν ἡ ὑπὸ τοῦ Θεοῦ οἰκοδομουμένη Ἐκκλησία. Ὀριγεν, Κατὰ Ματθαιον Ἐξηγητικων, Τομος ΙΒ'

If we say, as Peter, 'You are the Christ, The Son of the Living God,' 1 not as having it revealed by flesh and blood, but the light from our Father who is in heaven blazing in our hearts, we are made Peter, and  it will be said to us by the Word, 'You are Peter' and so on. For every disciple of Christ is a rock, from which drank those who drank from the spiritual stone which accompanied them, 2 and on every such stone is built the word of the Church, and by that is membership, for in each of those being perfected, that blessed gathering of perfecting words and deeds and thoughts, is the building up of the Church by God. Origen, Commentary on Matthew, Book 12 1 Mt 16.16 2 1 Cor 10.4
