Contradiction with Mark 16:8
This verse states that the women fled from the sepulchre trembling and amazed, saying nothing to anyone because they were afraid, which contradicts Matthew 28:8 where the women ran to bring word to the disciples.
Mark 16:8: And they went out quickly, and fled from the sepulchre; for they trembled and were amazed: neither said they any thing to any [man]; for they were afraid.
Contradiction with Luke 24:9-11
These verses suggest that the women reported the resurrection to all the eleven disciples and others, which provides some contradiction to the lively excitement in Matthew 28:8 by suggesting initial skepticism from the apostles towards their news.
Luke 24:9-11: And returned from the sepulchre, and told all these things unto the eleven, and to all the rest.
Paradox #1
Some people point out a contradiction between Matthew 28:8 and other gospel accounts about how the women reacted after discovering Jesus' empty tomb. In Matthew, the women leave with both fear and joy, ready to tell the disciples. In Mark 16:8, they leave trembling and upset, and initially tell no one because they are afraid. This difference in reactions is seen as an inconsistency.
