The question was posed as to why so few systematic theology books speak to an issue such as economics. Below is how Bojidar Marinov answered.

“Any area of practical study and application is deadly to anti-Theonomists, for it exposes their nakedness. If they want to be Biblical, they are forced to go to the Law of God, which makes them an easy target for Theonomists who point to their inconsistency. If they want to be faithful to their anti-Theonomic position, they have to rely on humanistic theories which can be easily exposed as anti-Biblical. If you go back and read Joel’s and mine articles against the Two Kingdoms rhetoric, you will see that most of the time all we need to do is wait for these guys to talk on some practical issue – economics, politics, law, etc. – and show how they go against their own theology.”

“Therefore, the safest bet for all these seminary rats is to exclude such issues from their systematic theologies in order to avoid exposing themselves as inconsistent and as theological hypocrites. Keep only obscure hyper-spiritualized irrelevant topics under the title of “theology,” and relegate life and action and practical thought to the realm of “natural law” and common grace.”
