The general uniformity of church organization among the Puritan plantations is the more remarkable in view of the notable independence and originality of the leading men, who represented tendencies of opinion as widely diverging as the quasi-Presbyterianism of John Eliot and the doctrinaire democracy of John Wise. These variations of ecclesiastico-political theory had much to do with the speedy diffusion of the immigrant population. For larger freedom in building his ideal New Jerusalem, the statesmanlike pastor, Thomas Hooker, led forth his flock a second time into the great and terrible wilderness, and with his associates devised what has been declared to be "the first example in history of a written constitution--a distinct organic law constituting a government and defining its powers."[102:1] The like motive determined the choice company under John Davenport and Theophilus Eaton to refuse all inducements and importunities to remain in Massachusetts, choosing rather to build on no other man's foundations at New Haven.[102:2] At the end of a hundred years from the settlement of Boston the shores and river valleys of Massachusetts and Connecticut were planted with towns, each self-governing as a pure democracy, each with its church and educated minister and its system of common schools. The two colleges at Cambridge and New Haven were busy with their appointed work of training young men to the service of God "in church or civil state." And this great and prosperous and intelligent population was, with inconsiderable exceptions, the unmingled progeny of the four thousand English families who, under stress of the tyranny of Charles Stuart and the persecution of William Laud, had crossed the sea in the twelve years from 1628 to 1640.
