You are about to find out if you know as much about the Catholic faith as you claim to know. Take it from me: your ego will suffer. But don't fall into despair. Most Catholics (some priests included, alas) will answer most of these questions incorrectly. For each question, choose the one answer which you think is most fully correct. There are no trick questions, but you must read very carefully. Terms are used in their precise meanings; don't be fooled into selecting a wrong answer by thinking in loose or colloquial terms. Each question has only one correct answer, and it might be "None of the above." Please go to the website above to find out why each possible answer is right or wrong.
