I’ve been staying away from this topic for a while because quite frankly, I just don’t live at that address any longer. But understanding that old (or as they might say “former”) friends read this blog, I figure it might be helpful to constructively point out some things I think might help them.
Legalists sometimes defend themselves by claiming that legalism, properly understood, is just what Paul condemned in Galatians 1: the sin of making justification conditional on some work or ceremony performed by the sinner. In other words, legalism is works-salvation. So, they say, if you formally affirm the principle of sola fide and preach that people can be saved without any prerequisite work, you can’t possibly be a legalist, no matter how many rules you make and impose on the consciences of people who are already converted.
No. Legalism is the error of abandoning our liberty in Christ in order to take on a yoke of legal bondage (Galatians 5:1). There are actually two kinds of legalism.
First is the one recognized and despised even by the fundamentalist with his thick rule-book. It’s the legalism of the Judaizers. The Judaizers wanted to make circumcision a requirement for salvation. They had fatally corrupted the gospel by adding a human work as a requirement for salvation. That is certainly the worst variety of legalism, because it destroys the doctrine of justification by faith and thereby sets up “a gospel contrary to the one you received” (Galatians 1:8-9).
But another kind of legalism is the legalism of the Pharisees. It’s the tendency to reduce every believer’s duty to a list of rules. This is the kind of legalism that often seems to surface in our comment-threads. At its root is a belief that holiness is achieved by legal meansby following a list of “standards.” This type of legalism doesn’t necessarily destroy the doctrine of justification like the legalism of the Judaizers. But it does destroy the doctrine of sanctification, and it is certainly appropriate to call it what it is: legalismi.e., a sinful misapplication of law; an attempt to make law do work that only grace can do. Like the Judaizers’ brand of legalism, it brings people under a yoke of bondage Scripture has not placed on them.

Pastor Robert Smith is facing a hard decision. Another Bible-believing pastor in his town has asked him to participate in a joint youth outreach emphasis. The difficulty is that Pastor Smith has some significant differences with the other church in terms of ministry philosophy and the practice of youth ministry. Although he does not wish to throw stones, he does not feel comfortable participating in the event. Pastor Smith is sure that some of his church members believe that he should publicly separate from the other church. Other members would see nothing wrong with participating, given that the gospel is more important than a church’s “parochial interests.”
