“Invite to the way of your Lord with wisdom and good instruction, and argue with them in a way that is best. Indeed, your Lord is most knowing of who has strayed from His way, and He is most knowing of who is rightly guided.” (Qur’an 16:125)
“If a prophet, or one who foretells by dreams, appears among you and announces to you a sign or wonder, and if the sign or wonder spoke of takes place, and the prophet says, “Let us follow other gods” (gods you have not known) “and let us worship them,” you must not listen to the words of that prophet or dreamer. TheLord your God is testing you to find out whether you love him with all your heart and all your soul. It is the Lord your God you must follow, and him you must revere. Keep his commands and obey him; serve him and hold fast to him. That prophet or dreamer must be put to death for inciting rebellion against the Lord your God, who brought you out of Egypt and redeemed you from the land of slavery. That prophet or dreamer of dreams tried to turn you from the way of the Lord your God commanded you to follow. You must purge the evil from among you. If your very own brother, or your son or daughter, or the wife you love, or your closest friend secretly entices you, saying, “Let us go and worship other gods” (gods that neither you nor your ancestors have known, gods of the peoples around you, whether near or far, from one end of the land to the other), do not yield to them or listen to them. Show them no pity. Do not spare them or shield them. You must certainly put them to death. Your hand must be the first in putting them to death, and then the hands of all the people. Stone them to death, because they tried to turn you away from the Lord your God, who brought you out of Egypt, out of the land of slavery. Then all Israel will hear and be afraid, and no one among you will do such an evil thing again.” (Deuteronomy 13:1-11)
“Jesus said, “But as for these enemies of mine, who did not want me to reign over them, bring them here and slaughter them before me.’”(Luke 19:27)
John Piper living in modern times with liberal sensitivities and modern concepts of “human rights” claims that he is dismayed with Protestant Theologian John Calvin’s decision to have Miachel Servetus burned alive for denouncing the Trinity.
