“His winnowing fan is in his hand to clear his threshing floor and to gather the wheat into his barn, but the chaff he will burn with unquenchable fire.” (Lk 3:17-18)
In the words of Origen:
“I should like to discover our Lord’s reason for holding a winnowing fan and to inquire into the nature of the wind that scatters the light chaff here and there, leaving the heavier grain lying in a heap—for you must have a wind if you want to separate wheat and chaff.
I suggest that the faithful are like a heap of unsifted grain, and that the wind represents the temptations which assail them and show up the wheat and the chaff among them. When your soul is overcome by some temptation, it is not the temptation that turns you into chaff. No, you were chaff already, that is to say fickle and faithless; the temptation simply discloses the stuff you are made of. On the other hand, when you endure temptations bravely it is not the temptation that makes you faithful and patient; temptation merely brings to light the hidden virtues of patience and fortitude that have been present in you all along. ‘Do you think that I had any other purpose in speaking to you,’ said the Lord to Job, ‘than to reveal your virtue?’ In another text he declares: ‘I humbled you and made you feel the pangs of hunger in order to find out what was in your heart.’”
Gerard Manley Hopkins expands upon this same verse in his poem Carrion Comfort, where he explores the purifying meaning of suffering in the spiritual life:
“Not, I'll not, carrion comfort, Despair, not feast on thee; Not untwist — slack they may be — these last strands of man In me ór, most weary, cry I can no more. I can; Can something, hope, wish day come, not choose not to be. But ah, but O thou terrible, why wouldst thou rude on me Thy wring-world right foot rock? lay a lionlimb against me? scan With darksome devouring eyes my bruisèd bones? and fan, O in turns of tempest, me heaped there; me frantic to avoid thee and flee?
Why? That my chaff might fly; my grain lie, sheer and clear. Nay in all that toil, that coil, since (seems) I kissed the rod, Hand rather, my heart lo! lapped strength, stole joy, would laugh, chéer. Cheer whom though? the hero whose heaven-handling flung me, fóot tród Me? or me that fought him? O which one? is it each one? That night, that year Of now done darkness I wretch lay wrestling with (my God!) my God.”
Being winnowed may not be the most enjoyable, pleasant experience. But it is an act of mercy on the part of the Son of Man, who longs to take us into his barn.
