Luke said that Jesus continued to proclaim or preach (καὶ ἦν κηρύσσων) his message in the synagogues of Judea (εἰς τὰς συναγωγὰς τῆς Ἰουδαίας). Mark, chapter 1:39, had something similar, but Mark said that it was Galilee and not Judea. Mark also said that Jesus was casting out demons. He seemed very intent on emphasizing that Jesus was casting out demons along with his undefined preaching. Matthew, chapter 4:23, was also somewhat similar, since Matthew implied that Jesus went all over Galilee, teaching in their synagogues. The synagogue was a new developing Jewish gathering place that might mean a group or assembly of Jewish people rather than a building, since some places may not have been able to afford a building. Matthew said that Jesus was proclaiming the good news or the gospel about the kingdom, without saying whether it was the kingdom of God, the kingdom of heaven, or even an earthly kingdom. What did Luke mean here by saying Jesus was in the synagogues of Judea, when the other two synoptics clearly stated that it was in Galilee? Actually, later in this work, Luke had Jesus go to Jerusalem.
This is another saying of Jesus, only found in Matthew, that carries on with the theme of the hypocrites. However, this time it is about prayer. When the followers of Jesus went to pray (Καὶ ὅταν προσεύχησθε), they should not be like the hypocrites (οὐκ ἔσεσθε ὡς οἱ ὑποκριταί) who love to stand praying in the synagogues and the street corners (ὅτι φιλοῦσιν ἐν ταῖς συναγωγαῖς καὶ ἐν ταῖς γωνίαις τῶν πλατειῶν ἑστῶτες προσεύχεσθαι). Just as they had done with their almsgiving, these hypocrites wanted to be seen by other men (ὅπως φανῶσιν τοῖς ἀνθρώποις). Certainly, there was the common times for prayer of the faithful Jews. The Greek word for hypocrites “οἱ ὑποκριταὶ” originally meant actors or someone who sought praise, while acting deceitfully. According to Matthew, these hypocrites were usually the enemies of Jesus. Just as about almsgiving, Matthew has Jesus give a solemn saying (ἀμὴν λέγω ὑμῖν) concluding that these men who sought human appeal have already received their reward (ἀπέχουσιν τὸν μισθὸν αὐτῶν). Is this a repudiation of public prayer?
The early followers of Jesus were his Jewish apostles and disciples. They formed a close-knit community. As they ventured out of Jerusalem after the death and resurrection of Jesus, they formed other small groups of Christian communities. During the first century of Christianity, we often refer to these Christians as the Primitive Christian Communities, not really a church yet, but described in the Acts of the Apostles. As far as we know, these Jewish followers of Jesus prayed in the Temple and the synagogues. They shared their stories about Jesus and his followers with other Jewish groups. Out of this oral community will come the written documents of the New Testament.
