Luke said that the friends of the centurion continued by saying he would not presume to come to Jesus (διὸ οὐδὲ ἐμαυτὸν ἠξίωσα πρὸς σὲ ἐλθεῖν). Instead, he wanted Jesus to only say the word (ἀλλὰ εἰπὲ λόγῳ), and thus his servant would be healed (καὶ ἰαθήτω ὁ παῖς μου). This saying of the centurion’s friends is exactly the same as the centurion himself in Matthew, chapter 8:8, perhaps indicating a Q source. The Roman centurion’s friends responded to Jesus that the centurion merely wanted Jesus to say the word, and then his servant would be healed. Perhaps, he was aware that Jewish people were not expected to go into the homes of gentiles like himself. Once again, this saying of the centurion and his friends has made its way into the Roman Catholic pre-communion prayer Eucharistic liturgy. Would you rely on the word of Jesus?
Here is the first of the sayings from the so-called Q source. Both Matthew, chapter 3:9-10, and Luke here have the exact same wording in their presentations of John’s preaching to the people. Instead of just the Pharisees and Sadducees, Luke has John address this to all the people coming to be baptized. This saying emphasized deeds, rather than relying on ancestry. They were to produce fruit that was worthy of repentance (ποιήσατε οὖν καρποὺς ἀξίους τῆς μετανοίας). They had to perform good deeds. They should not presume that because they have had Abraham as their father, as the privileged chosen ones (καὶ μὴ ἄρξησθε λέγειν ἐν ἑαυτοῖς Πατέρα ἔχομεν τὸν Ἀβραάμ), that all would go well for them. Then John pointedly said to them (λέγω γὰρ ὑμῖν) that God had the power (ὅτι δύναται ὁ Θεὸς) to change stones and rocks into the children of Abraham (ἐκ τῶν λίθων τούτων ἐγεῖραι τέκνα τῷ Ἀβραάμ), a Hebrew play on words that was translated into Greek. The axe was already lying at the foot of the trees, ready to go to work (ἤδη δὲ καὶ ἡ ἀξίνη πρὸς τὴν ῥίζαν τῶν δένδρων κεῖται). Every tree that was not bearing or producing good fruit would be cut down (πᾶν οὖν δένδρον μὴ ποιοῦν καρπὸν καλὸν ἐκκόπτεται). Then they would be thrown into the fire (καὶ εἰς πῦρ βάλλεται).
