Psalms 2:10

And again by Isaiah, “Who shall measure heaven with a span, and the whole earth with his hand?” Behold God’s greatness, and be filled with amazement. Let us worship Him of whom the prophet says, “Before Thy face the hills shall melt, as wax melteth before the fire!” This, says he, is the God “whose throne is heaven, and His footstool the earth; and if He open heaven, quaking will seize thee.” Will you hear, too, what this prophet says of idols? “And they shall be made a spectacle of in the face of the sun, and their carcases shall be meat for the fowls of heaven and the wild beasts of the earth; and they shall putrefy before the sun and the moon, which they have loved and served; and their city shall be burned down.” He says, too, that the elements and the world shall be destroyed. …

In Solomon: “The hardest judgment shall be made on those who govern. For to a mean man mercy is granted; but the powerful shall suffer torments mightily.” Also in the second Psalm: “And now, ye kings, understand; be amended, ye who judge the earth.”

9. You say that no example is found in the writings of evangelists and apostles, of any petition presented on behalf of the Church to the kings of the earth against her enemies. Who denies this? None such is found. But at that time the prophecy, “Be wise now, therefore, O ye kings; be instructed, ye judges of the earth: serve the Lord with fear,” was not yet fulfilled. Up to that time the words which we find at the beginning of the same Psalm were receiving their fulfilment, “Why do the heathen rage, and the people imagine a vain thing? The kings of the earth set themselves, and the rulers take counsel together against the Lord, and against His Anointed.” Truly, if past events recorded in the prophetic books were figures of the future, there was given under King Nebuchadnezzar a figure both of the time which the Church had under the apostles, and of that which she has now. …

210. But as to the calumnious charges which you bring against us, saying that by us the wrath of the kings of the world is excited against you, so long as we do not teach them the lesson of holy Scripture, but rather suggest our own desire of war, I do not imagine that you are so absolutely deaf to the eloquence of the sacred books themselves as that you should not rather fear that they should be acquainted with it. But whether you so will or no, they gain entrance to the Church; and even if we hold our tongues, they give heed to the readers; and, to say nothing of the rest, they especially listen with the most marked attention to that very psalm which you quoted. For you said that we do not teach them, nor, so far as we can help it, allow them to become acquainted with the words of Scripture: "Be wise now therefore, O ye kings; be instructed ye judges of the earth. …

Chapter 5. 19. But as to the argument of those men who are unwilling that their impious deeds should be checked by the enactment of righteous laws, when they say that the apostles never sought such measures from the kings of the earth, they do not consider the different character of that age, and that everything comes in its own season. For what emperor had as yet believed in Christ, so as to serve Him in the cause of piety by enacting laws against impiety, when as yet the declaration of the prophet was only in the course of its fulfillment, "Why do the heathen rage, and the people imagine a vain thing? The kings of the earth set themselves, and their rulers take counsel together, against the Lord, and against His Anointed;" and there was as yet no sign of that which is spoken a little later in the same psalm: "Be wise now, therefore, O ye kings; be instructed, ye judges of the earth. …

8. “Thou shalt rule them with a rod of iron,” with inflexible justice, and “Thou shalt break them like a potter’s vessel” ( ver. 9 ); that is, “Thou shalt break” in them earthly lusts, and the filthy doings of the old man, and whatsoever hath been derived and inured from the sinful clay. “And now understand, ye kings” ( ver. 10 ). “And now;” that is, being now renewed, your covering of clay worn out, that is, the carnal vessels of error which belong to your past life, “now understand,” ye who now are “kings;” that is, able now to govern all that is servile and brutish in you, able now too to fight, not as “they who beat the air, but chastening your bodies, and bringing them into subjection.” “Be instructed, all ye who judge the earth.” This again is a repetition; “Be instructed” is instead of “understand;” and “ye who judge the earth” instead of “ye kings.” For He signifies the spiritual …

5. “For, lo, the kings of the earth are gathered together” ( ver. 3 ). Behold now those sides of the North, see how they come, see how they say, “Come ye, and let us go up to the mountain of the Lord: and He will teach us His way, and we will walk in it.” “And have come together in one.” In what one, but that “corner-stone”? “They saw it, and so they marvelled” ( ver. 4 ). After their marvelling at the miracles and glory of Christ, what followed? “They were troubled, they were moved” ( ver. 5 ), “trembling took hold upon them.” Whence took trembling hold upon them, but from the consciousness of sins? Let them run then, king after a king; kings, let them acknowledge the King. Therefore saith He elsewhere, “Yet have I been set by Him a King upon His holy hill of Sion.”…A King then was heard of, set up in Sion, to Him were delivered possessions even to the uttermost parts of the earth. …

“And I will make Him my first-born; higher than the kings of the earth” ( ver. 27 ). Our Martyrs, whose birthdays we are celebrating, shed their blood on account of these things, which were believed though not yet seen; how much more brave ought we to be, as we see what they believed? For they had not yet seen Christ raised on high among the kings of the earth: as yet princes were taking counsel together against the Lord and His Anointed: what follows in the same Psalm was not then fulfilled, “Be wise now therefore, O ye kings: be learned, ye that are judges of the earth.” Now indeed Christ has been exalted among the kings of the earth.
