The Gospels tell of five Marys: Mary, the mother of Jesus; Mary Magdalene; Mary the sister of Laza
Matthew has Mary Magdalene and the Mary the mother of James and Joses at the scene of the crucifixion. Mark identifies the two same women at the scene. Luke simply says there were "the women that followed him from Galilee," but mentions no names. The only mention of Mary the mother of Jesus as being at the scene was made in the Gospel of John, along with Mary the wife of Cleophas and Mary Magdalene. This does not mean, of course, that the other Gospel accounts are incorrect in the matter of who was present. The Gospel accounts differ in other respects, too.
There is no mention of any Mary being seen along the route to Golgotha. Catholic tradition may have her there, but not the Bible. I'm not being argumentative, but try to use the Bible as my source in the matter.
This is all true, but WHAT mother would NOT be following her son as he marched along to his death?
(There are way too MANY modern mothers that are plopped down in front of the boob tube, soaking up the gospel of Oprah and Jerry, as their children march, metaphorically to THEIR deaths!
Well, since she is certainly placed at the crucifixion, one can deduce she followed her Son there.
