The two-hour rule applies if you ask me to all activities on Sunday. I am a woman and had to learn these things in RCIA as an adult. Making dinner, picking up after the kids and all sorts of stuff seemed like such little things and then I asked and was told that I could do these things, FIRSTLY if they were absolutely necessary, (i.e. you cannot leave your baby in pooey diapers till Monday logical common sense on that count) and SECONDLY even if absolutely necessary, the total time invested needs to remain below two hours. What that means to me is cooking on Saturday for Sundays and simply reheating, no shopping, not even on the Net and no chores at all. The toys can stay right where they are till Monday. Otherwise, I’m committing a mortal sin and need Confession before the Eucharist again. Not worth it. To me, studying is work and should also be limited. But this is just my spin on things, so do ask a reliable Priest not an ear-tickler. If you are sincere about not wanting to commit a mortal sin of working on Sundays, then you will find the Way to do all you need to do in the six days and nights provided. Just ask the Blessed Mother and you won’t go wrong.

P.S. For all those who only do things if they are found explicitly written in the current Canon Codes of 1983 are gonna have a hard time with what I wrote. Sorry if I offend but that is how it got taught to me and that is how I live it.
