I prefer the term "doctrine of grace" rather than Calvinism.
Me, too. However, many noncalvinists don't like it when calvinists use that term to describe what they believe. Some think it's dishonest—a way to trick people and not let them know we're really calvinists.
And others complain that it's not right for calvinists to take over that term, because noncalvinists believe in grace, too.
