O Christmas Sun! What holy task is thine! To fold a world in the embrace of God!

Addressing the “Christmas Sun” in apostrophe, the speaker treats the season’s light as a sacred agent rather than a mere natural phenomenon. The “holy task” suggests Christmas as a moment of spiritual illumination and reconciliation: the sun’s warmth and radiance become a metaphor for divine charity that can gather (“fold”) the whole world into God’s “embrace.” The image compresses theology into a domestic gesture—wrapping or enfolding—implying comfort, protection, and unity. Read this way, the couplet frames Christmas not primarily as festivity but as a universalizing act of grace, inviting the reader to see the holiday’s meaning in terms of inclusion and spiritual renewal.
