Freedom of religion is a principle that supports the freedom of an individual or community, in public or private, to manifest religion or belief in teaching, practice, worship, and observance. It also includes the freedom to change one's religion or belief.
Freedom of religion is considered by many people and most of the nations to be a fundamental human right.
It is interesting to compare this fundamental human right with what the Bible says - not least because many Christians claim humans rights come from God. From NASB:
Deuteronomy 13:6 “If your brother, your mother’s son, or your son or daughter, or the wife [e]you cherish, or your friend who is as your own soul, entice you secretly, saying, ‘Let us go and serve other gods’ (whom neither you nor your fathers have known, 7 of the gods of the peoples who are around you, near you or far from you, from one end of the earth to the other end), 8 you shall not yield to him or listen to him; and your eye shall not pity him, nor shall you spare or conceal him. 9 But you shall surely kill him; your hand shall be first against him to put him to death, and afterwards the hand of all the people. 10 So you shall stone him [f]to death because he has sought to seduce you from the Lord your God who brought you out from the land of Egypt, out of the house of [g]slavery. 11 Then all Israel will hear and be afraid, and will never again do such a wicked thing among you.
12 “If you hear in one of your cities, which the Lord your God is giving you to live in, anyone saying that 13 some worthless men have gone out from among you and have seduced the inhabitants of their city, saying, ‘Let us go and serve other gods’ (whom you have not known), 14 then you shall investigate and search out and inquire thoroughly. If it is true and the matter established that this abomination has been done among you, 15 you shall surely strike the inhabitants of that city with the edge of the sword, [h]utterly destroying it and all that is in it and its cattle with the edge of the sword. 16 Then you shall gather all its booty into the middle of its open square and burn the city and all its booty with fire as a whole burnt offering to the Lord your God; and it shall be a [i]ruin forever. It shall never be rebuilt.
Hmm, quite the opposite of religious tolerance. Kind of like human rights were invented by man, not God...
