Murder, adultery, and incest are bad.
(There, now are you satisfied? However, just because I am also against abortion doesn't mean that I am going to deny the Reformation and return to Rome either.)
The most important question, for you, is this: What if the Calvinists are correct? We believe that we are, and that we have "the mind of Christ". If so, it is not pride that states that we are correct, but the assurance that the Spirit of God has given us the right answers. If we are correct, that doesn't bode well for you. See, you think that mormons have some truth. We deny that, recognizing that (oops, if I really say what I want, then I will be banned for bashing). As a result, we don't think that half-truths are truths, they are falsehoods.
What if we are correct? I Corinthians 2:14.
Foolish rationalization that it was!
