Heresy is a logical and consistent system of belief that is in error. Luther had one. About you I cannot be sure based on what you posted. You may be a follower of heresy, but that does not necessarly make you a heretic. I know and love plenty of Protestants that have their beliefs for cultural reasons and never rejected the Church in their hearts, even though they dread the step that would bring them home to the Church. As was mentioned here before, heresy is a term of art. It does not apply to beliefs that err for lack of coherence.
I have rejected that part of your Church in my heart. I have many Catholic friends - so what. We are in disagreement over doctrine, doctrine, doctrine.
