Well, I
am a "good little Catholic" and sure enough, it listed Roman Catholicism as my first match. Must be that agreement that women should not be priests.

Here are the questions that I think specifically lead to a Catholic result...
#6: One is saved by God's grace through faith in Jesus Christ.
That's frustrating, because while we
do agree with the above we
also think that we have to cooperate with that grace. We do that by obeying Christ's response to the question, "What do we have to do to be saved?" and He said, "Keep the commandments".
#7: One must be a member of a specific church to be saved.
Again, the simplicity in the question is frustrating. Catholics do believe that our church contains the fullness of the faith that other denominations are missing, but how one is a "member" of the church makes for interesting theological discussions.
#11: Once saved always saved.
That one right there separates the Catholics from most Prostestants. Yes, we believe once
saved always saved, we just don't think that we are
assured of salvation until we die in a state of grace. Even after we accept Jesus Christ as our personal Lord and Savior we can throw that gift of grace away. Should we choose to do that we are not guaranteed of going to Heaven.
#16: Christ is physically present in Communion.
That's the most obviously Catholic question in the list. What separates the Roman Catholics from the others would be limiting the receiving of Communion to those at or past the age of reason... not infants.
#24: Only Scripture should be used as a rule of faith.
In 2 Thessalonians 2:15 St. Paul says, "Hold fast to the traditions which you have learned
whether by word or by our epistle.".
