Once upon a long ago, when we lived near the equator in a big house with a big yard and a big tree, the Poppy of the family decided to read the Bible from beginning to end. He had been looking for some sort of spiritual guidance for quite some time. The older daughter remembered a brief stint of worshiping African gods and saying a prayer for the ancestors.
Around 4, the older daughter an her LittleSister were told the family would no longer eat pork. This was a great disappointment, since her favorite meal in the whole world was bacon and eggs. "What do you want for breakfast" the mama would ask? "Bacon-and-eggs" said LittleGirl. Later on, Mama would ask "What do you want for supper?" "Bacon-and-eggs" LittleGirl would say. So when when the Poppy explained how they would no longer be eating bacon, since bacon came from pigs, she was not happy at all. But, she got used to it. They also started to keep the Sabbath Day.
Around the time LittleGirl was 6, the Poppy discovered that Sabbath was the seventh day, and the seventh day was Saturday. LittleGirl really wasn't happy about this AT ALL, since they lived in Jamaica and NOBODY came out to play on Sunday. So LittleGirl felt screwed out of two play days. But she had a LittleSister, so they played more together. In the end, they were probably closer because of it.
When LittleGirl was seven, the Poppy read about the first Passover in Exodus 12. He was very excited about it, and wanted to do it. The problem was that they didn't know any body with a Jewish Calendar. And also, it was already passed the 14th day of the first month--January. So the Poppy decided to hold a passover on the last day of the Passover--the 21st day of the first month. So they did. They got dressed and wore belts and shoes on their feet, ate lamb in haste and unleavened bread. This being Jamaica, the unleavened bread was called Johnny Cake.
Not very long after the family kept this first passover, the LittleGirl and her LittleSister woke up one Saturday morning to find their big house and their big yard swarming with marshalls, and their belongings being packed up into boxes, and the boxes being stacked on the sidewalk. Outside the big yard. They were being evicted from their big house with the big yard.
Like the Children of Israel, the little family traveled around, homeless, for about a year. Their faith in God grew, their strength as a family grew. Eventually they came to settle in a little house in the middle of a sandy stretch of land, right next to the ocean. They kept all the Holy Days, starting from the Passover, but since they had started on a regular Roman calendar, it ended up that they stuck to that Calendar. To "switch" in the middle seemed uncomfortable. And some 35 years later, they're still doing it the same way. It gets a little weird from time to time, trying to explain how it all came to be. But to switch now, after 35 years, just seems strange.
