Acts 15:1-17 “All One Family”


There are times when it is rather easy to tell that people are in different groups. For example, it is usually easy to tell a diet/exercise fanatic from a couch potato. We can have a hand inspection and probably tell who’s a blue collar worker and who is a white collar worker. Nationalities can sometimes be determined. Sometimes you can even tell a person’s denomination. If they are walking around with ashes on their forehead on Ash Wednesday, you know that they aren’t Baptist.

There are times, though, when it is very difficult for us to determine what an individual is or isn’t. What does a Christian look like? How do you know that a person is a Christian and when they are not a Christian? Who’s in the family and who isn’t? Our lesson today has the first church council, which took place in Jerusalem, meeting to determine answers to these very questions.


The conflict continues between the Gentile Christians and the Jewish Christians. A strong faction in the early church believed that people had to become Jews—be circumcised, eat Kosher, and observe the Sabbath, before they became Christians. The Gentile Christians argued that they only needed to have faith, and they did not need to follow the Jewish teachings.

Peter cast the deciding vote. He stands before the council and recalls his experience with Cornelius a Gentile who became a Christian. While Peter was still preaching to Cornelius and his household, the Holy Spirit descended upon Cornelius and his household and they were filled with the Spirit. This happened before Cornelius had a chance to become a Jew.

After deliberation, the council decided that the determining factor in being a Christian was faith. People did not need to become Jews before they could become Christians. This decision transformed Christianity in to a world religion, and gave us the Lutheran “battle cry” “We are justified (saved) by faith.”


When we talk about faith, it is important for us to remind ourselves that it is a gift. The Spirit descended upon Cornelius and his family, gave them faith, and filled them with his presence.

Faith isn’t something we can conjure up. We cannot create faith where once there was no faith. We cannot earn our faith.


The faith that the early Christians were talking about, though, is different from the way faith is popularly understood today. We place a great emphasis on believing the right things. Many people believe that faith believes that the Bible is inspired, Jesus rose from the dead, and that Jesus died for our sins. Or people think that you have faith when you come to the end of your reasoning: “I can’t explain it. Just have faith.” Faith wasn’t first understood as believing several theological points. The early Christians believed a person—they believed Jesus because he was a person with whom they had a relationship.
