Matthew gives us detail so that we can understand and believe. Fred Craddock in Preaching through the Christian Year C lists the questions that Matthew's account is answering: What happened to the body? Who prepared it? Where was it entombed? He reminds us of more evidence that Matthew gives: the body was put in a tomb, the tomb was sealed with a large stone, two women witnessed this, Roman guards kept watch.
We can't accept resurrection unless we accept death.
