I appreciate the sentiments in this article, and I agree that legalism is a problem for many. To be a legalist, though, is not to affirm the moral truth of the Law. Legalism is not the careful keeping of God’s Law. What legalism is, is to rely upon the Law a means to salvation. The problem with this article is that Rohr treats the Law as the problem, rather than sin (breaking the Law) as the problem. His concern over legalism leads him to deny the proper place of the Law. Rohr says that the Law is only “. . . to get you seriously engaged with the need for grace and mercy; they were never an end in themselves (read Romans 7:7ff).” This is missing the point of the Law.
"If you set up the abrogated duties of the law again, you are a legalist: if you set up the duties of the Gospel in Christ’s stead, in whole or in part, you err still."
