14 But they wonder that Christian powers are roused against detestable scatterers of the Church. Should they not be moved, then? How otherwise should they give an account of their rule to God? Observe, beloved, what I say, that it concerns Christian kings of this world to wish their mother the Church, of which they have been spiritually born, to have peace in their times. We read Daniel's visions and prophetical histories. The three children praised the Lord in the fire: King Nebuchadnezzar wondered at the children praising God, and at the fire around them doing them no harm: and while he wondered, what did King Nebuchadnezzar say, he who was neither a Jew nor circumcised, who had set up his own image and compelled all men to adore it; but, impressed by the praises of the three children when he saw the majesty of God present in the fire what said he?
“And I will publish a decree to all tribes and tongues in the whole earth.” What sort of decree? “Whosoever shall speak blasphemy against the God of Shadrach, Meshach, and Abednego, shall be cut off, and their houses shall be made a ruin.” See how an alien king acts with raging indignation that the God of Israel might not be blasphemed, because He was able to deliver the three children from the fire: and yet they would not have Christian kings to act with severity when Christ is contemptuously rejected, by whom not three children, but the whole world, with these very kings, is delivered from the fire of hell!
For those three children, my brethren, were delivered from temporal fire. Is He not the same God who was the God of the Maccabees and the God of the three children? The latter He delivered from the fire; the former did in body perish in the torments of fire, but in mind they remained steadfast in the ordinances of the law. The latter were openly delivered, the former were crowned in secret. It is a greater thing to be delivered from the flame of hell than from the furnace of a human power.
If, then, Nebuchadnezzar praised and extolled and gave glory to God because He delivered three children from the fire, and gave such glory as to send forth a decree throughout his kingdom, “Whosoever shall speak blasphemy against the God of Shadrach, Meshach, and Abednego, shall be cut off, and their houses shall be brought to ruin,” how should not these kings be moved, who observe, not three children delivered from the flame, but their very selves delivered from hell, when they see Christ, by whom they have been delivered, contemptuously spurned in Christians, when they hear it said to a Christian, “Say that you are not a Christian”? Men are willing to do such deeds, but they do not wish to suffer, at all events, such punishments.
