People were banished out of their town or country, their goods confiscated,their books burned, their bodies burned alive ; others were hanged,or branded on their foreheads, all for disputing with Rome's doctrine on "infant baptism"(yes, today its such a non-issue!), the eucharist, etc.and instead holding to the Gospel.
Fox's Book of Martyrs: an example of Rome
"Dominicus, a learned soldier, having read several controversial writings, became a zealous Protestant, and retiring to Placentia, he preached the Gospel in its utmost purity, to a very considerable congregation. One day, at the conclusion of his sermon, he said, "If the congregation will attend to-morrow, I will give them a description of Antichrist, and paint him out in his proper colors."
A vast concourse of people attended the next day, but just as Dominicus was beginning his sermon, a civil magistrate went up to the pulpit, and took him into custody. He readily submitted; but as he went along with the magistrate, he made use of this expression: "I wonder the devil hath let me alone so long." When he was brought to examination, this question was put to him: "Will you renounce your doctrines?" To which he replied: "My doctrines! I maintain no doctrines of my own; what I preach are the doctrines of Christ, and for those I will forfeit my blood, and even think myself happy to suffer for the sake of my Redeemer." Every method was taken to make him recant for his faith, and embrace the errors of the Church of Rome; but when persuasions and menaces were found ineffectual, he was sentenced to death, and hanged in the market place."
Rome hasn't changed its doctrines. To join hands with it is to tread upon the blood of those who wouldn't side with the RCC and its horrific doctrines to save their lives. They were willing to be TORTURED for biblical doctrine at the hands of Rome. Why are so many "Evangelicals" willing to bow to Rome for lesser causes?
