The question of whether it is a sin to work on Sunday is a matter of interpretation and religious belief. In many Christian traditions, Sunday is considered a day of rest and worship, and it is believed that it is important to set aside this day for religious activities.

However, the specific restrictions on work on Sunday can vary from denomination to denomination and from culture to culture. Some Christians believe that it is a sin to work on Sunday, while others believe that it is acceptable to engage in necessary work or activities that support the well-being of oneself or others.

Ultimately, the determination of whether working on Sunday is a sin is a personal matter, and it depends on one’s individual beliefs and religious practices. Some Christians may choose to avoid work on Sundays, while others may choose to engage in work that they believe is important and necessary.
