<p>4:18 <i>And they called them, and ordered them not to speak at all nor teach in the name of Jesus<em>- </em></i>This was only really of power and relevance if in fact Peter and John were still considered to be synagogue members. Likewise with Paul's beating with rods, which was a synagogue punishment (2 Cor. 11:25). Clearly the early believers remained within the apostate system of Judaism until they were thrown out of it; they were not required by the Lord to stop attendance in an apostate system as a condition of fellowship with Him. Forbidding them to teach sounds very much like forbidding them to stand up in the synagogue and give their opinion on Scripture- a right which was open to all synagogue members, and one which Paul so often used in order to introduce the Gospel to the Jews.</p>
