Mary did NOT see and touch Jesus before leaving the tomb and going to get the disciples. She left the tomb afraid, and probably not fully understanding, and so went to the disciples still thinking the worst. It wasn't till she returned with them and met Jesus at the tomb that she understood that Jesus wasn't just not there, but actually risen.
Actually, of bigger concern to me is Mark's account (16:8) "Trembling and bewildered, the women went out and fled from the tomb. They said nothing to anyone, because they were afraid." Even this I think can be harmonized with the other accounts:
1) Mary goes the tomb with the other women and discovers it empty. (Matthew 28:1, Mark 16:1-4, Luke 24:1-3, John 20:1-2)
2) An angel tells them what happened (Matthew 28:5-7, Mark 16:5-7, Luke 24:4-8, not in John)
3) They leave with some of the women scared to say anything, but Mary goes and tells the disciples (Matthew 28:8, Mark 16:8, Luke 24:9-11, not in John; also implied in Luke 24:23)
4) Mary returns with the disciples Peter and John to the tomb (not in Matthew, not in Mark, Luke 24:12, John 20:3-9)
5) Peter and John leave the tomb and return to the other disciples (not in Matthew, not in Mark, Luke 24:12, John 20:10)
6) Jesus appears to Mary (not in Matthew, Mark 16:9, not in Luke, John 20:11-17)
7) Mary returns to tell the disciples that she has seen the risen Lord (not in Matthew, Mark 16:10-11, not in Luke, John 20:18)
8) Jesus appears to the other women who had run from the tomb (Matthew 28:9-10, not in Mark, not in Luke, not in John)
9) Jesus appears to the disciples on the road to Emmaus (not in Matthew, Mark 16:12-13, Luke 24:13-35, not in John)
10) Jesus appears to the disicples in the Upper Room (not in Matthew, Mark 16:14, Luke 24:36-49, John 20:19-23)
Your try to harmonize the Resurrection narratives is filled with holes:
You claim (Mary did NOT see and touch Jesus before leaving the tomb and going to get the disciples. She left the tomb afraid, and probably not fully understanding)
Well, thank you very much for that quibble . Now would you care to answer the argument? Let's begin by getting your answers to some simple questions. They are all based on what Matthew's narrative said.
1. Did Mary M encounter an angel at the tomb?
2. Did the angel tell Mary M that Jesus had risen?
3. Did the angel tell Mary M to tell the disciples that Jesus would go before the disciples to Galilee?
4. Did Mary Magdalene run from the tomb with great joy?
5. Did Mary Magdalene meet Jesus as she was running to find the disciples?
6. Did Mary Magdalene touch Jesus?
If your answers are not yes to all of these questions, then you must have a reading comprehension problem.
You said in point 2 and 3 of you try to harmonize

2) An angel tells them what happened (Matthew 28:5-7, Mark 16:5-7, Luke 24:4-8, not in John)
3) They leave with some of the women scared to say anything, but Mary goes and tells the disciples (Matthew 28:8, Mark 16:8, Luke 24:9-11, not in John; also implied in Luke 24:23)
with all due respect,that is absured !!! You ask why?
in number (2) you claim that :An angel tells them what happened (Matthew 28:5)The angel said to the women, "Do not be afraid, for I know that you are looking for Jesus, who was crucified. 6He is not here;
he has risen, just as he said. Come and see the place where he lay. 7Then
go quickly and tell his disciples: 'He has risen from the dead.
in number (3) you claim that Mary goes alone and tells the disciples .
Question 1: What is she supposed to tell the disciples?
answer: What the angel tells them(Mary and the other women) what happened (is not here;
he has risen, just as he said)..
Question 2:what did she tell the disciples?
Answer : John (20:1)Early on the first day of the week, while it was still dark, Mary Magdalene went to the tomb and saw that the stone had been removed from the entrance. 2So she came running to Simon Peter and the other disciple, the one Jesus loved, and said, "
They have taken the Lord out of the tomb, and we don't know where they have put him!"
Nice try my friend
