Upon the sounding of the third trumpet “there fell a great star from heaven, burning as it were a lamp, and it fell upon the third part of the rivers, and upon the fountains of waters; and the name of the star is called Wormwood . ... and many men died of the waters, because they were made bitter” (Rev. 8:10-11). A star is the symbol of authority in government, not supreme (for this is represented by the sun), but subordinate, and one therefore, from the very emblem employed, who should have been the source of light and order to men. But he falls “from heaven,” from the place in which he had been set by God (for the powers that be are ordained of God); that is, he is now by his fall severed from all connection with God, though he still burns, not as a star, but as a lamp, and thus attracts by his light and radiance. He falls upon and corrupts all the sources — the moral sources, of life, as set forth by the rivers and fountains of waters. Accordingly his name indicates the effects of his action, for a third part of the waters (the sphere and range of his influence) become wormwood, bitter and poisonous to those who drink of them, and consequently many die. (Compare Deut. 29:18; Prov. 5:4.) An illustration of such an effect may often be seen when one who has been prominent in the church of God becomes unfaithful or apostate, and morally destroys his hearers by infidel teachings. In manifold ways it is possible for those who have fallen from high places, whether among men or in the church, to poison the sources of life, and it is just this that will take place on a grand scale at the fall of the star Wormwood.
