It is clear that there were some Israelites who posed as believers in and keepers of the covenant with Yahweh, while inwardly they did not believe and secretly practiced false religions, and even tried to spread them (cf. Deut. 13:6–11). To protect the kingdom from such hidden heresy, these secret practitioners of false religions had to be rooted out and expelled from the community. This directive from the Lord applied even to whole cities that turned away from the true religion (Deut. 13:12–18). Like Israel, medieval Europe was a society of Christian kingdoms that were formally consecrated to the Lord Jesus Christ. It is therefore quite understandable that these Catholics would read their Bibles and conclude that for the good of their Christian society they, like the Israelites before them, “must purge the evil from the midst of you” (Deut. 13:5, 17:7, 12). Paul repeats this principle in 1 Corinthians 5:13.
These same texts were interpreted similarly by the first Protestants, who also tried to root out and punish those they regarded as heretics. Luther and Calvin both endorsed the right of the state to protect society by purging false religion. In fact, Calvin not only banished from Geneva those who did not share his views, he permitted and in some cases ordered others to be executed for “heresy” (e.g., Jacques Gouet, tortured and beheaded in 1547; and Michael Servetus, burned at the stake in 1553). In England and Ireland, Reformers engaged in their own ruthless inquisitions and executions. Thousands of English and Irish Catholics were put to death—many by being hanged, drawn, and quartered—for practicing the Catholic faith and refusing to become Protestant. An even greater number were forced to flee to the Continent. We point this out to show that both sides understood the Bible to require the use of penal sanctions to root out false religion from Christian society.
The fact that the Protestant Reformers also created inquisitions to root out Catholics and others who did not fall into line with the doctrines of the local Protestant sect shows that the existence of an inquisition does not prove that a movement is not of God. Protestants cannot make this claim against Catholics without having it backfire on themselves.
What about the Jews who were practicing Jews?
Protestants, whom the Catholic church had put out guidance to kill, put their own parishioners in the crosshairs of what happened as England fought back against The Unholy Pope’s edicts.
Aside from the Muslim attacks, everything else from Protestants and Jews was simply a counter move against what The Unholy Catholic church started first through killings and torture.
In two hundred years, the Unholy Catholic church will have a similar webpage to talk to the circumstances around the sexual perversions of its hierarchy from today's headlines. It, too, will be fabricated to biblically justify a few occasions it occurred, while saying the practice was minor and practiced as much or more so by Protestants. After all, that is what propaganda is supposed to do.
Meaning such Protestants were acting like Catholics had and did for so long, and had much more to unlearn from them.
The fact that the Protestant Reformers also created inquisitions to root out Catholics and others who did not fall into line with the doctrines of the local Protestant sect shows that the existence of an inquisition does not prove that a movement is not of God.
It certainly does not prove that Protestantism is not of God since it has no central leadership and as a whole movement it did not sanction the unholy use of the sword of men (the victims of which were sometimes Protestant), whereas in Roman Catholicism submission to a supreme earthly head is required.
And which required of RC rulers to exterminate in the territories subject to their jurisdiction all heretics pointed out by the Roman Church, and sanctioned the torture of even suspected witnesses to extract confession.
And while this itself does not proves an entire movement is not of God, Scripture proves that the "movement" to use to the sword of men in order to suppress theological dissent is not of God. For the only wholly inspired substantive authoritative record of what the NT church believed is Scripture, especially Acts thru Revelation, and in which distinctive Catholic teachings are not manifest .
