I guess I am a terrorist. Maybe you have read about the FBI's investigations into "traditional Catholics" as terrorists. They are wrong in one way, and right in another. They are wrong because I have no desire to create terror in anyone. I do, however, have a desire to cause people to have a healthy and godly fear of eternal judgment, and do so in a way that will cause them to repent and turn to Christ.
They are right because they are terrified of us. They see us as "terrible" and as something to be fearful of. If they only knew Who they were really attacking when they attack God's Church (cf. Acts 9:1-6) they would be even more terrified than they already are. They may not receive their full punishment in this world, but they will surely receive it in the next. May God have mercy on their souls.
