"If you are going to criticize a Theology, you should know what it teaches... Many Protestants who criticize Roman Catholicism often don't know what Catholicism teaches because they have read Dave Hunt, Jack Chick or outdated books on the subject."
Regarding understanding your opponent, let's use this example.
I understand RC's dogmas of Mary from a Catholic perspective, (veneration, not worship,dulia vs. latria, the new Eve, Queen of Heaven, Mother of God, Co-Redemptrix, assumption, immaculate conception and all that.)
I've read Catholic articles, and listened to Catholic radio, watched Journey Home on EWTN, but, for all my undertanding of every nuance, I still consider the Catholoic dogma of Mary false, blasphemous doctrines.
How would you respond to an RC who said "If you still don't accept the dogmas of Mary, you just don't understand them well enough?"
