In the gospel of Johns version of Jesus cleansing the temple, Jesus yells, Stop turning my Fathers house into a market! (2:16). The temple was sacred; the market was secular. Modern-day economists threaten to change the sacred into the secular when they analyze the church, marriage, and other holy things using purely secular models such as utility maximization. Economic models are useful and powerful when they are used to analyze secular things; however, when they are used to analyze sacred things, they tend to make those things less than what God intended them to be. Furthermore, because Christians are the temple of God (1 Cor. 3:16 and 6:19), each Christian needs to be personally vigilant to keep the secular from invading and destroying the sacred.
