The Apostles traveled in small groups to baptize in the Name of the LORD. One group traveled to Antioch (part of Syria in those days…present day part of Turkey). They came to the people of Antioch with a letter.
Acts of the Apostles 15: 23-29 This is the letter delivered by them: “The apostles and the presbyters, your brothers, to the brothers in Antioch, Syria, and Cilicia of Gentile origin: greetings. Since we have heard that some of our number [who went out] without any mandate from us have upset you with their teachings and disturbed your peace of mind, we have with one accord decided to choose representatives and to send them to you along with our beloved Barnabas and Paul, who have dedicated their lives to the Name of our LORD Jesus Christ. So we are sending Judas and Silas who will also convey the same message by word of mouth: ‘It is the decision of the Holy Spirit and of us not to place on you any burden beyond these necessities, namely, to abstain from meat sacrificed to idols, from blood, from meats of strangled animals, and from unlawful marriage. If you keep free of these, you will be doing what is right. Farewell.'”
