Originally a heretic was any person who disagreed with the authority of the Pope, and the doctrine established by the Catholic Church. There doctrines consisted of such things as: The authority of the Pope, Sunday Sabbath, Trinitarianism, Hell, saints, images, and so on.
The Greek term is found in the Bible, and Mondar is correct in its meaning. It refers to a Christian who disagrees with accepted Christian teaching and causes schism because of his or her personal opinion.
Thus, it is not "any" person who disagrees with the "authority of the Pope", since Muslims disagree with the authority of the Pope, but are not considered heretics. Heretics come from inside the community...
What is important to note is
HOW a reformer reacts to tensions when the institutional church reacts to what they believe is a problematic teaching.
What does the reformer do when confronted with such difficulties?
Luther would have been a great Catholic saint, had his reaction been more in line with St. Catherine of Sienna, who had no qualms in attacking the heirarchy, even the Pope, but always affirming the underlying authority of the Church. (This is quite a statement, given that this saint was a WOMAN during the 1400's - recall how women were treated then, but the Church recognized her as a saint.)
Unfortunately, Luther refused to hear the Church, and so was then considered a "heathan man and a publican", as per the words of Jesus Christ Himself... (Matt 18:17)
