Sometimes, the simplest answer to give is, as Alex did, when facing childish personal attack in the church against reformed doctrines, is just to say, "I stand on the shoulders of Giants: Calvin, Luther, etc.".
But then one must be careful, not to use this as an excuse for lazy defense. For one must care enough to deal with the corrupt minds, those that make wrong right and right wrong before God, the proud ones, the wicked, the selfish ones and so on. The problem is not solved by merely stating "I stand behind these heroes, so you deal with them, not me".
