Obeying the law of the land is a commandment of God. So let me ask you, which takes priority obeying the decree to practice polygamy or obeying the commandment of God to abide by the laws of the nation?
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.
Peter makes his comment in response to the charges of the high priest, who was teaching the gospel of man rather than Christ. As far as I can see, there is no law being broken here by Peter.
Col. 3: 22
22 Servants, obey in all things [your] masters according to the flesh; not with eyeservice, as menpleasers; but in singleness of heart, fearing God:
Servants were told to obey their masters out of the fear of God. Why is that? Because we are to obey the laws of the land and at that time it was legal to be owned as a slave.
Titus 3: 1
1 PUT them in mind to be subject to principalities and powers, to obey magistrates, to be ready to every good work,
There it is, be subject to pricipalities and powers. Translation: obey the law of the land.
Heb. 13: 17
17 Obey them that have the rule over you, and submit yourselves: for they watch for your souls, as they that must give account, that they may do it with joy, and not with grief: for that [is] unprofitable for you.
Again, obey those who rule over you. Or in other words obey the laws of the land.
