Contradiction with John 19:38
This verse states that Joseph of Arimathea was a disciple of Jesus, but secretly for fear of the Jews, whereas Matthew 27:57 simply describes him as already being a disciple without mentioning secrecy.
John 19:38: And after this Joseph of Arimathaea, being a disciple of Jesus, but secretly for fear of the Jews, besought Pilate that he might take away the body of Jesus: and Pilate gave [him] leave. He came therefore, and took the body of Jesus.
