“Should we Evangelize Protestants?”
To what end? What is your intent in the evangelization?
Let me guess, "To make them a Francis hater; too!"?
I think Jesus mentioned...
Matthew 23:15"Woe to you, teachers of the law and Pharisees, you hypocrites!You travel over land and sea to win a single convert, and when he becomes one,you make him twice as much a son of hell as you are.
