Let us remember that assertions like these, which to Christians now may seem obviously futile, by no means necessarily seemed so then. Then, much more than now, pagan enquirers after JESUS would be sure to be conscious that the true salvation offered was, in one sense, emphatically a Jewish salvation. It was the message which told of the life and death, the person and work, of One who _was_, "after the flesh," a Jew. It was the announcement that the long hope of _Israel_ was fulfilled in Him. Its terminology was full of words and ideas altogether Jewish. And its messengers--above all, for the Philippians, St Paul--were Jews, of unmistakable nationality, training, and (doubtless) appearance. On a first view, on a hasty and shallow view certainly, it may have seemed a quite natural incident in such a message when some of its propagandists asserted that to reach this Hebrew Deliverer and King the enquirer must form a connexion in religion which should be definitely Hebrew. It is conceivable that even yet, in the history of the Church, this phase of error may in some form assert itself again. We look in the future, it may be in the near future, for the keeping to the old Israel of promises which have never been revoked. We believe that Rom. xi. shall yet find its fulfilment, and that the "receiving of them again shall be life from the dead" to the world. In that great period of blessing, the work of missions may (shall we not say, probably will?) be very largely taken up by Hebrew Christians. And if any of these, like some of their predecessors of the first age, should have only a distorted view of the Gospel of Christ, their intense national character may tell not a little on the form of their message. But this is by the way. All that is really before us here is the fact that--not the open hostility of unconverted Jews but--the sidelong counter-action of Judaistic Christians was threatening Philippi, and must be met by the Apostle.
