Luke parallels Stephen’s and Jesus’ situations … they preached in a way unpopular with the religious leaders, were taken before the Sanhedrin, were unjustly accused with false testimony.
The charges that Stephen depreciated the importance of the temple and the Mosaic law and elevated Jesus to a stature above Moses (⇒ Acts 6:13-14) were in fact true. Before the Sanhedrin, no defense against them was possible. With Stephen, who thus perceived the fuller implications of the teachings of Jesus, the differences between Judaism and Christianity began to appear.
