Irenaeus of Lyons, Against Heresies 4.33

Such is the spiritual disciple who truly receives the Spirit of God. From the beginning, in all the arrangements of God, this Spirit was present to men: he announced future things, he showed present things, he narrated past things. He judges all, yet he himself is judged by no one.

For he judges the nations, creatures who serve the Creator more than the Oreator, and who with a reprobate mind consume their whole operation in vain. And he judges the Jews as well, who do not perceive the word of liberty, nor are willing to go forth free, though they have the present Liberator. Instead they pretend to serve outside the law at an unseasonable time, acting as if God needed nothing, and they do not know the advent of Christ, which he accomplished for the salvation of men, nor are they willing to understand. For all the prophets announced his two advents.

The first advent: he was made man in affliction, knowing how to bear infirmity; he sat on a foal of an ass; he was the stone rejected by the builders; like a sheep he was led to sacrifice; by the extension of his hands he overthrew Amalek. He gathered the scattered sons from the ends of the earth into the fold of the Father; he remembered his own dead who had fallen asleep, and he descended to them so that he might raise them up.

The second advent: he will come upon the clouds, bringing the day that is like a burning clibanus. He will strike the earth with the word of his mouth, and with the spirit through his lips he will kill the impious. He will hold a winnowing fan in his hand, and he will purify his threshing floor; he will gather the wheat into his barn, but he will burn the chaff with inextinguishable fire.
