This is the only mention in Scripture of the seraphim. I do not need to enter upon the much-debated, and in some respects interesting, question as to whether these are to be taken as identical with the cherubim, or as to whether they are altogether imaginary and symbolical beings, nor as to whether they are identical with the angels, or part of their hierarchy. All that may be left on one side. I would only notice, before I deal with the specific words of my text, the significance of the name. It means 'the flaming' or 'burning ones,' and so the attendants of the divine glory in the heavens, whether they be real or imaginary beings, are represented as flashing with splendour, as full of swift energy, like a flame of fire, as glowing with fervid love, as blazing with enthusiasm. That is the type of the highest creatural being, which stands closest to God. There is no ice in His presence, and the nearer we get to Him in truth, the more we shall glow and burn. Cold religion is a contradiction in terms, though, alas, it is a reality in professors. And so with that explanation, and putting aside all these other questions, let us gather up some, at least, of the lessons as to the essentials of worship, and try to grasp the prophecy of the heavenly state, given us in these words. I. The Wings of Reverence. He covered his face, or _they_ covered _their_ faces, lest they should see. As a man brought suddenly into the sunlight, especially if out of a darkened chamber, by an instinctive action shades his eyes with his hand, so these burning creatures, confronted with the still more fervid and fiery light of the divine nature, fold one pair of their great white pinions over their shining faces, even whilst they cry 'Holy! Holy! Holy! is the Lord God Almighty!' And does not that teach us the incapacity of the highest creature, with the purest vision, to gaze undazzled into the shining light of God? I, for my part, do not believe that any conceivable extension of creatural faculties, or any conceivable hallowing of creatural natures, can make the creature able to gaze upon God. I know that it is often said that the joy of the future life for men is what the theologians call 'the beatific vision,' in which there shall be direct sight of God, using that word in its highest sense, as applied to the perceptions of the spirit, and not of the sense. But I do not think the Bible teaches us that. It does teach us 'We shall be like Him, for we shall see Him as He is.' But who is the 'Him'? Jesus Christ. And, in my belief, Jesus Christ will, to all eternity, be the medium of manifesting God, and there will remain, to all eternity, the incapacity which clogs creatures in time--' No man hath seen God at any time, nor _can_ see Him.'
