The main question to be answered is, Whom do these "souls" represent? Are they Christian martyrs, suffering perhaps at the hands of the Jews before the fall of Jerusalem, perhaps at the hands of the world to the end of time? Or are they the martyrs of the Old Testament dispensation, Jewish martyrs, who had lived and died in faith? Both suppositions have been entertained, though the former has been, and still is, that almost universally adopted. Yet there can be little doubt that the latter is correct, and that several important particulars of the passage demand its acceptance. 1. Let us observe how these martyrs are designated. They had been slain _for the word of God, and for the testimony which they held_. But that is not the full expression of _Christian_ testimony. As we read in many other passages of the book before us, Christians have "the testimony _of Jesus_."[144] The addition needed to bring out the Christian character of the testimony referred to is wanting here. No doubt the saints of old looked forward to the coming of the Christ; but the testimony "of Jesus" is the testimony pertaining to Him as a Saviour come, in all the glory of His person and in all the completeness of His work. It is a testimony embracing a full knowledge of the Messiah, and the inference is natural and legitimate that it is not ascribed to the souls under the altar, because they neither had nor could have possessed it. 2. The cry of these "souls" is worthy of notice, _How long, O Master, the holy and the true_, where the word "Master," applied also in Acts iv. 24 and Jude 4[145] to God as distinguished from Christ, corresponds better to the spirit of the Old than of the New Testament dispensation. 3. The time at which the martyrs had been killed belongs not to the present or the future, but to the past. Like all the other Seals, the fifth is opened at the very beginning of the Christian era; and no sooner is it opened than the souls are seen. It is true that the Seer might be supposed to transport himself forward into the future, and, at some point of Christian history more or less distant, to console Christian martyrs who had already fallen with the assurance that they had only to wait _a little time_, until such as were to be their later companions in martyrdom should have shared their fate. But such a supposition is inconsistent with the fact that St. John in the Apocalypse always thinks of the Christian age as one hardly capable of being divided; while, as we shall immediately see more clearly, it would make it impossible to explain the consolation afforded by the bestowal of the _white robe_. 4. The altar under which the blood is seen may help to confirm this conclusion, for that blood is not preserved in the inner sanctuary, in that "heaven" which is the ideal home of all the disciples of Jesus: it lies beneath the altar of the outer court.
