I agree, for those that truly want to understand, I'm certain that through prayer, that can be achieved. A very good resource for explanations from a Protestant point of view are Dr. Scott Hahn's writings. He understands that perspective, and can address differences. Too many Catholic lay people only know basics about our own faith, much less about other faiths, to be able to defend false allegations.
We really should do a better job, because it is obvious that there are too many false prophets out there, bearing false witness, about other Christians.
Amen.
