Hopkins wrote an Easter greeting for people who are worn out. His audience is not a cheerful holiday crowd but those who have spent forty days of Lent hungry, cold and punishing themselves, and who now come to receive communion. The central idea is that such hardship is not wasted. It will be repaid in kind: rough cloth becomes gold-threaded folds, burnt-down flames are refilled with oil, and tired knees are made strong.
The form helps carry that promise. This is a Petrarchan sonnet, with an octave rhymed ABBAABBA and a sestet rhymed CDCDCD. The octave is a single long address, built from a run of "you" phrases: "you striped in secret," "you whom the East… so nips," "you serged fellowships," "you vigil-keepers." It reads like a priest's eye moving down a line of communicants, giving each a brief portrait. The sestet turns from description to promise, and its key verb is "shall." The rhythm is mostly steady iambic pentameter, but Hopkins roughens it where the subject is rough. "Crooked rough-scored chequers" is clotted with hard consonants, so the line seems to scrape. The consoling lines are softer: "myrrhy-threaded golden folds of ease" is all long vowels and murmuring sounds, and the ease it names can be heard in the words.
The imagery keeps returning to the body. "Pure fasted faces" and "Lenten lips" are alliterative and almost tasteable, and God arrives "all sweetness" to a mouth that has gone without. Then the poem darkens. The phrase "breath-taking whips" plays on two senses, since the blow knocks the wind out of you and the phrase also sounds like the word for wonder. Whether the whips are literal or a figure for self-denial, the poem leaves open. What matters is what it does with the marks: those "crooked rough-scored chequers" criss-cross like scars, and they "may be pieced / To crosses." Pain becomes raw material, to be assembled into something holy.
Hopkins also uses line endings to enact what he describes. The cold nips the people "whom the East / With draught of thin and pursuant cold," and the sentence is blown across the line break like the wind itself. Then comes a small piece of wordplay. Those same people "Breathe Easter now," and the word "East" sits inside "Easter." The poem suggests that the biting direction the cold comes from holds the seed of the feast.
The sestet turns on cloth and light. The octave's "serged fellowships" are followed by "sackcloth and frieze" (both coarse fabrics) and "the ever-fretting shirt of punishment," where "fretting" suggests a garment that rubs and irritates. These are exchanged for golden folds. Likewise the vigil-keepers' "low flames decreased" find their answer in the promise that God will "o'er-brim the measures you have spent / With oil of gladness." Judging by the imagery, the spent measures are lamp oil, so the burnt-down vigil is topped up to the brim. The word "spent" quietly admits that the cost was real.
The last line is the plainest. "Lo, God shall strengthen all the feeble knees" has an old, biblical ring, and it follows "Your scarce-sheathed bones are weary of being bent." Bent bodies suggest kneeling and penance, and the final line straightens them. The word "all" matters too, because no one in the line is left out.
The poem is significant for what it chooses not to do. It does not leap straight into triumph. It spends its first half honouring the fatigue, the cold and the marks, and only then offers relief, so the joy feels earned. It also shows Hopkins's habit of packing language tightly, with coined or fused compounds like "breath-taking," "scarce-sheathed," "o'er-brim" and "myrrhy-threaded," which make each phrase do double work. Within fourteen lines it turns a season of hardship into something gentle, and it keeps the hardship in view the whole way through.
