inconsistency between this and those other scriptures in which God is represented as alone the Rock of our salvation. The Bed-Rock, "the Rock of Ages," is here, as elsewhere, God as revealed in His Son, and Peter is the first stone "well and truly laid" upon it. If the surroundings suggest the use of the words _Petros_ and _Petra_, stone and rock, the circumstances suggest the use of the word Ecclesia, or Church, which is here employed by our Lord for the first time. Up to this time He has spoken always of the kingdom, never of the church. How is this to be explained? Of course the kingdom is the larger term; and now it is necessary that that portion of the kingdom which is to be organised on earth should be distinguished by a specific designation; and the use of the word "church" in preference to the more familiar "synagogue" may be accounted for by the desire to avoid confusion. Besides this, however, the word itself is specially significant. It means an assembly "called out," and suggests the idea of separateness, so appropriate to the circumstances of the little band of outcasts. To see into this more fully, let us recall the recent teaching as to the true Israel (chap. xv.), no longer to be found in the old land of Israel. If there is to be an Israel at all, it must be reconstituted "outside the camp." In view of this, how strikingly significant is it that just as Abraham had to leave his country and go to a strange land to found the old theocracy, so Christ has to leave His country and go with His followers to these remote northern regions to constitute "_the Israel of God_," to inaugurate His Church, the company of those who, like these faithful ones, come out and are separate to be united by faith to Him! Christ with the Twelve around Him is the Israel of the New Testament; and we can imagine that it was on this occasion especially that in the prayers which we know from St. Luke's Gospel He offered in connection with this very conversation, He would find these words of devotion especially appropriate: "Behold, I and the children which God hath given Me" (Heb. ii. 13). The family of God (see chap. xii. 49) are by themselves apart, disowned by those who still bear unworthily the name of Israel; and most appropriate it is that on this occasion our Lord should begin to use that great word, which means first "called out" and then "gathered in": "on this rock I will build My CHURCH."
