   • 1849, Henoch Clapham, quoted in Jane Eliza Leeson, Chapters on Deacons

     First, order gone, and doores not being kept, / By baptisme heaps of prophane do rush. / With them, at length, a ministry incrept, / That with the horn God's ordinance did push.

     It seemed a thing for weeping / To find, at slumber's wane / And morning's sly increeping, / That Now, not Then, held reign.
