Peter's words receive no answer, for, while he is speaking, another solemn and silencing wonder has place. Suddenly a strange cloud forms in the cloudless sky. It is 'bright' with no reflection caught from the sun; it is borne along by no wind; slowly it settles down upon them, like a roof, and, bright though it is, casts a strange shadow. According to one reading of Luke's account, Christ and the two heavenly witnesses pass within its folds, leaving the disciples without, and that separation seems confirmed by Matthew's saying that the voice 'came out of the cloud.' Our evangelist points to its brightness as singular. It was not merely bright, as if smitten by the sunlight, but its whole substance was luminous. It is almost a contradiction to speak of a cloud of light, and the anomalous expression points to something beyond nature. We cannot but remember the pillar which had a heart of fire, and glowed in the darkness over the sleeping camp, and the cloud which filled the house, and drove the priests from the sanctuary by its brightness. Nor should we forget that at His Ascension Jesus was not lost to sight in the blue; but while He was yet visible in the act of blessing, 'a cloud received Him out of their sight.' It is, in fact, the familiar symbol of the divine presence, which had long been absent from the temple, and now reappears. We may note the beauty and felicity of the emblem. It blends light and darkness, so suggesting how the very same 'attributes' of God are both; and how His revelation of Himself reveals Him as unrevealable. The manifestation of His power is also the 'hiding of His power.' The inaccessible light is also thick darkness. The same characteristics of His nature are light and joy to some, and blackness and woe to others. We may note, too, Christ's passage into the cloud. Moses and Elijah, being purged from mortal weakness, could pass thither. But Jesus, alone of men, could pass in the flesh into that brightness, and be hid in its fiery heart, unshrinking and unconsumed. 'Who among us shall dwell with everlasting burnings? His entrance into it is but the witness to the purity of His nature, and the absence in Him of all fuel for fire. That bright cloud was 'His own calm home, His habitation from eternity,' and where no man, compassed with flesh and sin, could live, He enters as the Son into the bosom of the Father.
