I have been having bad luck lately with jobs, and this older Nigerian lady at the library asked if I would tutor her on MS word and typing, etc. She just got a job at a school and needs help with typing up tutorials, etc. I agreed of course. Anyway, I met up with her one Sunday really quick and just typed up something fast for her. She paid me $5. Was it a sin that I took the money and/or ‘worked’ on a Sunday? I did work for her today (Saturday), and she wants me to help her tomorrow (Sunday) also. Would it be a sin to technically work and accept money on Sunday?
No it is not a sin. If you have doubts such as these, get a regular confessor who can help you form your conscience and avoid scrupulosity.
