Now, while it is quite true that no given number of believers in any given place can be called "the body of Christ," or "the assembly of God;" yet they should be gathered on the ground of that body and that assembly, and on no other ground. We call the reader's special attention to this principle. It holds good at all times, in all places, and under all circumstances. The fact of the ruin of the professing Church does not touch it. It has been true since the day of Pentecost; is true at this moment; and shall be true until the Church is taken to meet her Head and Lord in the clouds, that "_there is one body_." All believers belong to that body; and they should meet on that ground, and on no other. [XXI.] The reader will need to ponder the distinction between the Church viewed as "the body of Christ," and as "the house of God." He may study Eph. i. 22; I Cor. xii. for the former. Eph. ii. 21; I Cor. iii.; I Tim. iii. for the latter. The distinction is as interesting as it is important. [XXII.] The reader will do well to note the fact that, in Matt. xvi., we have the very earliest allusion to the Church, and there our Lord speaks of it as a future thing. He says, "On this rock I _will_ build My Church." He does not say, "I _have_ been, or I _am_ building." In short the Church had no existence until our Lord Christ was raised from the dead and glorified at the right hand of God. Then, but not until then, the Holy Ghost was sent down to baptize believers, whether Jews or Gentiles, into one body, and unite them to the risen and glorified Head in heaven. This body has been on the earth since the descent of the Holy Ghost; is here still, and shall be until Christ comes to fetch it to Himself. It is a perfectly unique thing. It is not to be found in Old Testament Scripture. Paul expressly tells us it was not revealed in other ages; it was hid in God, and never made known until it was committed to him. (See, carefully, Rom. xvi. 25, 26; Eph. iii. 3-11; Col. i. 24-27.) True it is--most blessedly true--that God had a people in Old Testament times. Not merely the nation of Israel, but a quickened, saved, spiritual people, who lived by faith, went to heaven, and are there "the spirits of just men made perfect." But the Church is never spoken of until Matt. xvi., and there only as a future thing. As to the expression used by Stephen, "The Church in the wilderness" (Acts vii. 38), it is pretty generally known that it simply refers to the congregation of Israel. The _termini_ of the Church's earthly history are Pentecost (Acts ii.), and the rapture (I Thess. iv. 16, 17). THE CHRISTIAN HIS POSITION AND HIS WORK. PART I.
