What is legalism?

I have just finished Derek Thomas’ short work, How the Gospel Brings Us All the Way Home, in which he considers what Romans 8 teaches us about sanctification. At Faith, we enjoy exploring how the gospel fuels our Christian growth on a moment-by-moment basis. Derek’s book is very helpful. You should also consider Part Three of our Introduction to Faith seminar (see the calendar for dates).

Derek offers this reflection on page 49:

 

“The word legalism is overused. Sometimes I tell my students at the seminary where I teach that they may use this word once a year and no more. All too often legalism is employed whenever we consider obedience inconvenient. Legalism then becomes a “scare tactic word” masking an underlying indifference or mistrust of radical holiness.

What does legalism really mean? It is the proper word whenever one of the following is true:

  • I am being asked to obey in order to win God’s favor. A works-based view of salvation is essentially legalistic.
  • I am being asked to obey a command over and above that which God has given to me in the Bible. Essentially, I am being asked to obey against my conscience, which is subject to Scripture alone: “All members of this church must refrain from growing facial hair,” for example, is an example of legalism.
  • I am obeying God’s commandments from impure motives. When the older brother in the parable of the prodigal son viewed his obedience as a form of slavery, his obedience was legalistic.”
