Until a couple of years ago, the terms “Sabbath” and “Lord’s Day” stressed me out. I would either hear them used to make me feel bad about eating lunch at a restaurant on Sundays, supposedly against the instruction of the Puritans who I loved, or used to denounce the legalistic Sabbatarianism of the Puritans. The former was from Reformed acquaintances I didn’t know very well and felt shunned by, the inheritors of Puritan theology. The latter came from Baptist friends who I trusted but now felt pressured by to criticize the Puritans on something I hadn’t studied yet . . . In the conversations I was hearing, the Sabbath or Lord’s Day connoted anything but rest.
