The document is a 1630 sermon by John Winthrop titled "A Modell of Christian Charity" where he lays out a spiritual blueprint for the Puritan settlers, urging them to form a tight-knit "community" and uphold values of justice, mercy, and mutual aid so that their city on a hill will shine as an example to the world. Winthrop wanted the new community to live as the light of the world by coming together as one united body under God's sovereignty and delighting in each other through hard and good times alike.
