This is a post that contains several elements that does not alter our faith in any manner but allows us to speculate about its relevance to us.
We believe that Jesus resurrected on the third day after his crucifixion on Good Friday. If Jesus had chosen he could have resurrected on Good Friday before midnight, or on Holy Saturday that was the Sabbath, however he waited three days before he rose from the dead.
Jesus has a divine nature. The relevance to the resurrection on the third day may be associated with the body and the soul. It is the reason Catholics did not cremate the dead.
In the baptismal vows our godparents say when we are baptised there are words in the creed that include ‘And in one catholic and apostolic Church. I confess one baptism for the remission of sins. And I look for the resurrection of the dead. And the life of the world to come. (The Saint Andrew Daily Missal)
That reference to the resurrection is our resurrection from the dead and the life of the world to come.
There are members of our church who believe that because we are not divine we require more than three days to resurrection from the dead. Some believe we require nine days. With that belief the abstinence from eating meat, from lighting fires to cook, continues for 9 days. And community members continue to assist the bereaved family for nine days,
Others believe that our resurrection from the dead requires 30 days and they sustain the assistance to the bereaved family for that length of time.
Where this leads us to is the the rule that we are not allowed to cremate our dead. Because we are not fully knowledgeable about the length of time we require to release or separate our souls from our bodies.
