Sonnet 68 (Spenser)
Harrowing of Hell
Medieval Christian doctrine: between crucifixion and resurrection, Christ descended to hell to free the righteous dead. This is Easter theology, not just resurrection.
Captivity paradox
Wordplay from Ephesians 4:8—Christ takes captivity itself captive. The captives in hell become captors of us (in a good way), binding us to salvation.
Reciprocal love
The turn: from Christ's love for us to our obligation to love each other. 'All lyke deare' means everyone equally precious because equally bought with blood.
Final couplet shift
Breaks from addressing Christ ('Lord') to addressing his beloved ('deare loue'). The religious lesson becomes the marriage lesson—both are about love.
