The Christians of the Early Centuries were often misunderstood by their persecutors. They were often feared and hated. People usually fear and hate what they do not understand. Unlike the others who worshiped their gods in the temples, the Early Christians had no temples because they understood that their bodies were the temple of the Holy Spirit. When people got to know the Christians, then their fear and hatred dissipated.
We saw through Sacred Scripture that the first place the Apostles preached were in the synagogues. The Apostles were Jewish. The good news was spread in the synagogues first, but the Jews didn't like the Apostles preaching to them, so they were kicked out of the synagogues.
Then they preached to the Gentiles. The first people who called themselves "Christians" were the converts in Antioch. Christianity grew among the Gentiles like wildfire. So, brothers be humble. Our mission is to spread the Gospel of Christ to the entire world. Our mission is to be the light of the world so that those who see the light of Christ in us can also praise God our Father. Our mission is to be the salt of the earth. This salt dies so that others may live.
