John 11:43

And when He had thus spoken, &c. First, to show this voice to have great and prevailing authority, by which He was raising up Lazarus from death, as God ruling nature and death. Whence Cyril says, His command is kingly, and worthy of God: Lazarus, come forth. For He said this not as praying, but as bidding and commanding. A loud voice, then, signifies the great force and power which recalled Lazarus from death to life. For this was a most difficult work, and therefore required supreme and Divine power, as also a fitting voice. Symbolically and mystically, the cause was, to represent with this loud voice the trumpet-voice of the Archangel in the day of judgment, by which all the dead shall be raised. Whence SS. Chrysostom, Cyril, Theophilus, Euthymius, assert that Christ here willed to show in action what He had said in v. 25, "The hour is coming and now is, when the dead shall hear the voice of the Son of God, and they who hear shall live." Hear S. Ambrose (De Fide Resur.): The Lord shows thee in what manner thou shalt rise. For He did not raise up one Lazarus only, but the faith of all; and if, when thou readest, thou believest this, thy mind also, which was dead, receives life with that Lazarus. For what means it that the Lord drew near to the tomb, and cried with a loud voice: Lazarus, come forth, unless that He might afford us a specimen, might give us an example, of the future resurrection? Why did He cry aloud with His voice, as if He were not accustomed by His Spirit alone to perform [mighty works], as if He were not accustomed to command without speech? but that He might show what is written, "In the twinkling of an eye, at the last trump, the dead shall be raised. incorruptible" (1Co 15:52).

Typically, the loud voice of Christ signifies the great impulse of arousing grace, by which the sinner needs to be called forth from the custom of evil in which he lies buried, to grace and a new life. So S. Augustine. Hence Ephesians 5:14, "Awake thou that sleepest, and arise from the dead, and Christ shall give thee life."

Lazarus. He calls him by his proper name: lest, as says S. Ambrose, he might seem as one raised up for another, or his resurrection more by chance than by command. Again, He addresses the dead man as living, because all the dead live unto God, says S. Chrysostom.

Come forth. Not as if thou wert already risen, and only now wast to show thyself beyond the sepulchre, as Origen wrongly infers from hence: but, Rise, return from the dark and hidden caves of death and Hades; return, 0 soul of Lazarus, from the farthest limits of the Limbus Patrum into this body, and thence into the life, air, and light common to all living beings.
