So far it appears that no one is visiting this topic who believes the crucifixion took place on the 6th day of the week, and who thinks that the "heart of the earth" is referring to the tomb or at the earliest to the time the Messiah's spirit left His body, and who tries to explain the lack of a third night by saying He was employing common figure of speech/colloquial language. But maybe there will be someone sometime in the future.
