If I say to you 2+3=7 and you say, "untrue," have you called me a liar or corrected what you see as an error on my part?
I made a statement, you corrected me, I recognized the validity of your correction.
To my knowledge Protestants make no claim concerning the coverage of Bible reading during Church Services. Protestants are expected to read the Bible at home and/or during Bible Study.
What would compel you to ask such an unrelated question?
Your insinuation was that the ONLY place a Catholic read the Bible was in Mass, this would be a false assumption. Therefore, it makes just as much sense for me to infer that without hearing it in Church that a Protestant might not read the whole Bible. So yes, if your question is valid, so is mine.
