While we have these testimonies of Lactantius and Ambrose, when we come to examine the standard of Constantine, we find the accounts of both authors fully borne out; we find that that standard, bearing on it these very words, "Hoc signo victor eris," "In this sign thou shalt be a conqueror," said to have been addressed from heaven to the emperor, has nothing at all in the shape of a cross, but "the letter X." In the Roman Catacombs, on a Christian monument to "Sinphonia and her sons," there is a distinct allusion to the story of the vision; but that allusion also shows that the X, and not the cross, was regarded as the "heavenly sign." The words at the head of the inscription are these: "In Hoc Vinces [In this thou shalt overcome] X." Nothing whatever but the X is here given as the "Victorious Sign." There are some examples, no doubt, of Constantine's standard, in which there is a cross-bar, from which the flag is suspended, that contains that "letter X"; and Eusebius, who wrote when superstition and apostacy were working, tries hard to make it appear that that cross-bar was the essential element in the ensign of Constantine. But this is obviously a mistake; that cross-bar was nothing new, nothing peculiar to Constantine's standard. Tertullian shows that that cross-bar was found long before on the vexillum, the Roman Pagan standard, that carried a flag; and it was used simply for the purpose of displaying that flag. If, therefore, that cross-bar was the "celestial sign," it needed no voice from heaven to direct Constantine to make it; nor would the making or displaying of it have excited any particular attention on the part of those who saw it. We find no evidence at all that the famous legend, "In this overcome," has any reference to this cross-bar; but we find evidence the most decisive that that legend does refer to the X. Now, that that X was not intended as the sign of the cross, but as the initial of Christ's name, is manifest from this, that the Greek P, equivalent to our R, is inserted in the middle of it, making by their union CHR. The standard of Constantine, then, was just the name of Christ. Whether the device came from earth or from heaven--whether it was suggested by human wisdom or Divine, supposing that Constantine was sincere in his Christian profession, nothing more was implied in it than a literal embodiment of the sentiment of the Psalmist, "In the name of the Lord will we display our banners." To display that name on the standards of Imperial Rome was a thing absolutely new; and the sight of that name, there can be little doubt, nerved the Christian soldiers in Constantine's army with more than usual fire to fight and conquer at the Milvian bridge. In the above remarks I have gone on the supposition that Constantine acted in good faith as a Christian. His good faith, however, has been questioned; and I am not without my suspicions that the X may have been intended to have one meaning to the Christians and another to the Pagans. It is certain that the X was the symbol of the god Ham in Egypt, and as such was exhibited on the breast of his image. Whichever view be taken, however, of Constantine's sincerity, the supposed Divine warrant for reverencing the sign of the cross entirely falls to the ground.
