Acts 5 v 27 And when they had brought them, they set them before the council: and the high priest asked them,28 Saying, Did not we straitly command you that ye should not teach in this name? and, behold, ye have filled Jerusalem with your doctrine, and intend to bring this man’s blood upon us. 29 Then Peter and the other apostles answered and said, We ought to obey God rather than men. 30 The God of our fathers raised up Jesus, whom ye slew and hanged on a tree. 31 Him hath God exalted with his right hand to be a Prince and a Saviour, for to give repentance to Israel, and forgiveness of sins. 32 And we are his witnesses of these things; and so is also the Holy Ghost, whom God hath given to them that obey him.
Here the high priests are enforcing Sharia law. They are a form of secular or worldly government. Just as the Romans were. In that sense we as Christians make no distinction between secular and Sharia law. They are both of this world and man-made. They must both be resisted where they clash with biblical laws.
