Theologically, the demand for “circumcision” can take many forms, even today. It appears whenever one thinks along these lines: “Faith in Christ is fine as far as it goes, but your relation to God is not really right and your salvation not adequate unless…” It does not matter how the sentence is completed. Whenever such fine print is introduced to qualify trust/faith, there is “circumcision,” and Paul’s defense of the adequacy of trust/faith can come into its own again. The Galatian situation is never far; in fact, it is all too familiar.
