Puritan Work Ethic:
“The Puritans declared the sanctity of all honorable work. In so doing, they rejected a centuries-old division of callings into “sacred” and “secular”… This Puritan rejection of the dichotomy between sacred and secular work has far-reaching implications.It judges every honorable job to be of intrinsic value, and integrates every vocation with a Christian’s spiritual life. It makes every job consequential by regarding it as the arena for glorifying and obeying God and for expressing love (through service) to a neighbor.”
Off topic, but this is not a Puritan distinctive at all. Read any Catholic spiritual manual, and you find this point hammered over and over and over again: do your menial tasks with joy in a state of prayer. They are your means of sanctification in this life.
