What does Matthew 28:2 mean?
By comparing Matthew's telling of this event with the other Gospels, it seems clear that this earthquake and the appearance of the angel took place before the women arrived. Matthew's emphasis in his writing is on what happened, mostly grouping his information by theme. He's not as specific about when things happened, in minute order. He has mentioned the women coming to the tomb (Matthew 28:1), but then makes these comments as an aside: this is what had happened prior to women arriving. Likewise, it's not clear if the arrival of the angel caused the great earthquake or if they just happened at the same time. The angel, though, is the one who rolls the stone away. He then sits on it.It's important to notice that Matthew does not say that the angel rolled the stone away so Jesus could get out. In His glorified body after the resurrection, physical objects will not be a barrier to Jesus (John 20:19). Rather, the stone is removed so that the women and the disciples can enter the tomb and see that Jesus' body is gone.
