I have said that he did not understand the design of the vision; for, while he was hearing, from the mouth of Moses and Elijah, that the time of Christ’s death was at hand, he foolishly dreamed that his present aspect, which was temporary, would endure for ever. And what if the kingdom of Christ had been confined in this way to the narrow limits of twenty or thirty feet? Where would have been the redemption of the whole world? Where would have been the communication of eternal salvation? It was also highly absurd to conceive of Moses and Elijah as companions of the Son of God, as if it had not been proper that all should be reduced to a lower rank, that he alone may have the pre-eminence. And if Peter is satisfied with his present condition, why does he suppose that earthly supports were needed by those persons, the very sight of whom, he imagined, was enough to make him happy?

John Calvin on Peter’s response to the transfiguration. The sad reality is that many of our desires, if fulfilled as we wish, would result in the Kingdom of God being limited to the “narrow limits of twenty or thirty feet.” May God expand our vision and enlarge our capacity to embrace the cross.
