Paul did not tell Jews they must reject those practices which formerly set them apart, but rather that they must accept Gentiles as coequals without imposing upon them the obligation to keep Jewish ceremonial distinctives. The problem at Galatia, then, could not have been the observance of days per se because Jewish Christians were never told that they could not celebrate their distinctive calendar. Rather, the problem was that some were teaching that Gentiles could not be saved unless they, too, observed all the Jewish ceremonial distinctives. I, Paul, tell you that if you let yourselves be circumcised, Christ will be of no value to you at all. Paul couldn t care less about days per se, just as he couldn t care less about circumcision.
Circumcision is nothing and uncircumcision is nothing.
Keeping God's commands is what counts. The only thing that counts is faith expressing itself through love. Consequently, there is nothing in Paul s argument in Galatians which would lead us to believe that the observance of days per se was wrong, evil, unacceptable. What he was battling for was a Gospel which held out to the whole world a free and accessible salvation, one not tied to Jewish distinctives. But that leaves us with the question of whether the church is permitted to observe certain days in honor of our Lord.
