I know most of the people on this forum are against preaching heresy in public, but beyond that, how far, exactly, should the repression go? Can scholars within the privacy of academia discuss such matters unhindered?  How about just people in their own homes, or private meeting places?  Where would you draw the line, exactly?

I think if, lets say, a protestant is preaching heresy in public...and a Catholic priest passes by...then the priest should not get involved. There is no point in trying to stop someone from committing heresy in a case like that. It would only cause conflict. It goes no where. Its pointless.

As a matter of fact, I can't see any point in trying to correct any protestant for that matter.

The best you can do is realize that the protestant is your Christian brother (given that he/she is baptized properly), and that you must love him/her. Scripture says that you must love even your enemy. I am not saying that protestants are our enemies, but we must love them as well.

I personally believe that heresy is like no other mortal sin. You must meet the 3 requirements for you to be culpable for a mortal sin. We can only hope that the protestant who commits heresy does not meet all of the requirements.

Perhaps to counter the sin of heresy we should pray for them.
