By all the eagle in thee, all the dove.

The line juxtaposes two emblematic birds—eagle and dove—to evoke a union of seemingly opposed qualities: the eagle’s height, strength, and piercing vision with the dove’s gentleness, purity, and peace. In Crashaw’s devotional idiom, such paired images often serve to praise a sacred figure (or the sanctified soul) as simultaneously ardent and tender, powerful and meek. Read this way, the phrase functions like an invocation or blessing: it calls upon the “eagle” within (aspiration, spiritual intensity) without losing the “dove” (charity, humility). Its compact antithesis is characteristic of metaphysical religious lyric, where paradox becomes a vehicle for spiritual wholeness.
