On the Hebridean islands of Lewis and Harris, Sundays remain sacred, with businesses mostly closed and a strong tradition of church attendance. Recent debates over Sunday opening hours for stores like Tesco highlight the clash between modern conveniences and age-old customs. Scholars and local clergy emphasize the cultural importance of Sabbath observance, influenced by evangelical revivals. While changes such as Sunday flights and restaurants have emerged, the islands’ residents maintain that their spiritual and cultural connection to Sunday worship remains vital.
