I totally forgot about the fasting rule this morning, and I had pancakes before going to Mass. I had the last pancake around 8:50. During Mass I had the Eucharist but I don’t know the exact time. It was the 9:30 Mass.
During the RCIA session after Mass I realized I totally forgot that you need to fast an hour before receiving the Eucharist. Did I commit a mortal sin, or did I commit a venial sin because I was forgetful?
