The burial of Christ is now added, as an intermediate transition from the ignominy of the cross to the glory of the resurrection. True, indeed, God determined, for another reason that Christ should be buried, that it might be more fully attested that he suffered real death on our account.
But yet it ought to be regarded as the principal design, that in this manner the cursing which he had endured for a short time began to be removed; for his body was not thrown into a ditch in the ordinary way, but honorably laid in a hewn sepulchre.
Although at that time the weakness of the flesh was still visible and the divine power of the Spirit was not clearly seen before his resurrection; yet God determined by this, as a sort of preparation, to shadow out what he was shortly afterwards to do, that he might exalt gloriously above the heavens his Son, the conqueror of death.
