Some interesting observations about Mary of Bethany just to get us started (happy to hear from anyone out there who is interested in this subject!):
John 11:28: is this the only place in all four Gospels that Jesus asks to see someone?? (the someone, of course, being Mary - although it is interesting that we only learn of this through Martha and not from Jesus directly)
Mary appears just three times in the Gospels, but each time, she is kneeling at Jesus' feet. (In John 12, she goes one better and anoints His feet.) This is, of course, the traditional posture of a rabbinical student at the feet of the Master - except that only males were allowed to be rabbinical students at the time. Anointing of feet is an entirely different subject, to be explored later...
In all three appearances, Mary does something that violates religious or cultural norms. In Luke 10, she assumes the position of a scholar at Jesus' feet (which, as noted above, is traditionally for men only) and ignores the traditional female role in the kitchen (prompting criticism from Martha). In John 11, she is presumably sitting shiva for Lazarus' death (did the tradition exist then?), but she leaves the house when Jesus calls her. In John 12, she not only presents Jesus with an extravagant gift, but does so rather scandalously, by unbinding her hair (unheard of for a woman to do in front of any male other than her husband) and using it to wipe His feet (prompting criticism from Judas).
Of course, Mary's scandalous anointment echoes that of the "immoral woman" of Luke 7:37, which has resulted in much confusion of Gospel female identity over the centuries. Centuries of tradition holds that the unnamed "immoral woman" is Mary Magdalene, but there is no scholarship to support this and most NT scholars doubt it. The similarity between the act of the "immoral woman" and Mary's anointing in John has also led to a tradition of identifying them as the same woman, or just treating all three - Magdalene, Mary of Bethany and the "immoral woman" - as the same woman (known as Mary Magdalene), presumably to avoid confusion (or to create more!). And so we arrive at the sexist root of much historic NT scholarship that treats all women as fungible/interchangeable and unimportant. As we will see, Mary of Bethany and Mary Magdalene both occupy very different (but equally important) roles in the Incarnation.
In two of Mary's appearances, she is criticized by the truly clueless (Martha and Judas), but is defended by Jesus (Martha gets a gentle rebuke, Judas a harsher one). Jesus' defenses of Mary are fascinating and will be examined in detail later. Note that each time, He aligns Mary with Himself, implying that she possesses knowledge of a mystery that is otherwise known only to Him (!!).
Since Mary and Jesus seem to have quite a meaningful relationship, why is Mary not present at the Cross? As noted above, for nearly two thousand years - from about the fourth century until the 1960s - the Roman Catholic Church expressly taught that Mary of Bethany and Mary Magdalene were the same person, apparently because (among other things) Mary's absence from Calvary could not otherwise be explained - although clearly Martha and Lazarus weren't there either. All Christian traditions today acknowledge that Mary of Bethany and Mary Magdalene are two different women, but for some reason, just about all Christian theology pertaining to women is based upon Mary Magdalene. Much prayer and meditation has discerned a solution to the why-is-she-not-at-the-Cross issue, which will be discussed later.)
While it's true that Mary (or Maryam, or Miriam) was a common name in first century Israel, it's still no coincidence that the three women who figure most prominently in the three stages of Our Lord's Incarnation - His birth/Incarnation, His life/ministry, and His death/Resurrection) - are all named Mary. (again, more to come on this)
Finally, it's worth noting that throughout the Gospels, Jesus us always teaching, preaching, rebuking, correcting... except when it comes to Mary. (Jesus doesn't even hesitate to shut down His own mother! See Luke 8:21, John 2:4) As far as Jesus is concerned, Mary can do no wrong - even when she IS wrong (and I think she does get it wrong in John 11:32 - what do you think?) - when Mary is forlorn and weeping in this chapter, instead of correcting her, Jesus' emotional response is reminiscent of Psalm 18:7-20 - in other words, He races to her rescue (and Lazarus is raised).
