It's just Catholic, not Roman Catholic. Roman is an epithet first commonly used in England after the protestant revolt to describe the Catholic Church. It is never used by the official Catholic Church. A heretic that spoke out against the Church and refused to recant and submit would most often be punished with excommunication. The Church, of course, always tried to save the person first as she is the Body of Christ and is here for the sole purpose of bringing people to salvation, but if she fails in that, she excommunicates in an attempt to limit the damage done, as she did with Martin Luther and other heretics of that era.
Martin Luther was considered a heretic by the Catholic Church.
Copernicus
I hardly think the Catholic Church would proclaim him as a saint since the Church considers him to be a heretic.
William Tyndale did not reform the Catholic Church, he left it and was excommunicated as a heretic.
No, instead he was excommunicated as a heretic.
.Catholic AnswerThe Lutheran Ecclesial Community did not "break away" from the Catholic Church. It was founded by Martin Luther, a heretic who left the Catholic Church in the sixteenth century and was excommunicated.
A heretic.
.Roman Catholic AnswerMost of the people who protested against the Church in the sixteenth century were heretics and apostates. Today they are, more politically correct, known as "protestant reformers" by those who followed them.
John Wycliffe was dissident Catholic back in the 14th century, he translated that Bible into English and, in general, wrote against the Catholic Church. Martin Luther was a dissident in the 16th century who left the Catholic Church as a heretic and apostate and translated The Bible into German.
I think Martin Luther was declared a heretic not Martin Luther King.Martin Luther King, the American civil rights leader, was never declared a heretic by the Catholic Church.His namesake, Martin Luther, a 15th century Catholic monk, was however declared a heretic for teaching ideas and holding positions the Catholic Church understood to be false and a danger to the Faith as taught by the Church. His failure to stop his teaching of matters opposed to Catholic doctrine also brought him the penalty of being excluded from the Catholic community of believers, thus excommunicated.
In 1500 the Roman Catholic Church was all powerful in western Europe. There was no legal alternative. The Catholic Church jealously guarded its position and anybody who was deemed to have gone against the Catholic Church was labelled a heretic and burnt at the stake. The Catholic Church did not tolerate any deviance from its teachings as any appearance of 'going soft' might have been interpreted as a sign of weakness which would be exploited.
Heresy is a crime against the Christian church. Someone who commits a heresy is a heretic.
