Molecular biologist Michael Behe described living systems made of several interacting parts, whereby the removal of one part would disrupt the functioning of the whole, as irreducibly complex. Both creation scientists and intelligent design proponents highlight examples of irreducible compexity in their studies.
Calvinism is also irreducibly complex. It is an integrated hermeneutical system that is interconnected, just as each book of the Holy Scriptures is interconnected. You cannot divide the five parts of Calvinism without the entire system collapsing upon itself.
Calvinism is a theological system that cannot be broken down into parts, because there is only one point Calvinism is making, not five. The one single point that Scripture is making as interpreted by true and full Calvinists is that God is sovereign in all things, not some things. There are indeed five components of Calvinism, but they are so bound to each other that anyone who thinks he can pick and choose some points and leave out the other points will arrive at something that is not Calvinism.
Therefore Christians who consider themselves three or four point “Calvinists” should find a new name to describe what they believe about election. Confusion and misinterpretation will result in any attempt to reduce Calvinism to less than five components.
This statement should not imply that the three or four point evangelical is not a Christian; he is simply not a Calvinist.
