(Luk 4:14) And Jesus returned in the power of the Spirit into Galilee: and there went out a fame of him through all the region round about.
(Luk 4:15) And he taught in their synagogues, being glorified of all.
(Luk 4:16) And he came to Nazareth, where he had been brought up: and, as his custom was, he went into the synagogue on the sabbath day, and stood up for to read.
(Luk 4:28) And all they in the synagogue, when they heard these things, were filled with wrath,
(Luk 4:29) And rose up, and thrust him out of the city, and led him unto the brow of the hill whereon their city was built, that they might cast him down headlong.
(Luk 4:30) But he passing through the midst of them went his way,
(Luk 4:31) And came down to Capernaum, a city of Galilee, and taught them on the sabbath days.
Sabbarians tell us that we must do as Christ did, since he is our example. They point to these passages to show that we need to keep the Sabbath. Yet, although Christ was circumcised, most Sabbatarians don’t teach that circumcision is compulsory for Christians.
These are texts that supports the idea that Christians did NOT keep the Sabbath. You just need to look at CONTEXT. Luke is writing to … who? The GENTILE CHRISTIANS. So, why does he have to actually mention in his text that it was Jesus’ CUSTOM to go to the synagogue on the Sabbath. Jesus lived under the Old Covenant, and naturally he observed the Sabbath. Any Sabbath observance that Jesus did would have to explained to people who did not keep the Sabbath and who were unfamiliar with it. And therefore, when we see that Jesus’ Sabbath visit to the synagogue was actually explained, we need to ask WHY it needed to be explained. And, if we look at what the Bible and history show about first century Gentile Christians, we see that Luke needed to explain Jesus’ Sabbath customs because the Christian Gentiles were not familiar with the Sabbath at all. So, surprise! The text used to prove that Jesus went to the synagogue on the Sabbath, actually helps prove that Christians do NOT need to do that!!!
There is nothing in this text to even suggest that future Christians ought to keep the Sabbath at all.
