Nor all America can claim him now: Forevermore he is Mankind's and God's.

The couplet contrasts national ownership with a larger, transnational claim. By saying “Nor all America can claim him now,” the speaker rejects the idea that a great figure—most likely a recently dead hero or martyr—belongs to any single country. Death (and the moral meaning attached to the person’s life) transfers him into a universal register: “Mankind’s,” as a shared human exemplar, and “God’s,” as ultimately beyond worldly possession. The diction suggests elegy and canonization: the individual’s significance is framed as enduring and spiritually ratified, implying that true greatness outgrows patriotic boundaries and becomes part of humanity’s common moral inheritance.
