I am, and have always been, Jewish, but I was raised in a household with a father who was secularly Christian. We “celebrated” Christmas and Easter, but never went to church. We put up a tree but did not speak of Jesus. We colored eggs but did not discuss resurrections.
As a kid, Shabbat meant brisket. I loved that. Every once in a while, my mother would get inspired and feel the need to… cook? No, she always cooked in those days. It wasn't until many years later that dinner was more likely to be ordered than made.
