Ok, here is a question that if anyone here knows the answer to, I'll be seriously impressed.
Why is it that the Catholic church has branded Mary Magdalene a prostitute even though nothing in scripture supports that?
Because the bible is not always clear on WHICH Mary it is refering to. The only way your notions of Mary Magdalene are accurate is if we assume that there were three or four different mary's throughout the bible instead of just assuming there were two.
For example, John's Gospel mentions a "Mary" washing jesus feet with oils in the week or so before his death (The famous Judas speech about wasting money on Jesus that could have been given to the poor), and in a VERY similar account Luke (7:37) describes a VERY similar sceene and refers to the woman as a 'sinner'. Also, it has been suggested that no unmarried woman outside of a prostitute would be able to purchase expensive oils such as those.
Some say this was not Mary Magdelene but Martha's sister, and there is good evidence that they were 2 seperate people. But I am still showing the reference here to show what others would argue that the two are the same Mary.
In luke 8:2 there is talk of evil spirits leaving Mary's body (clearly a sign of former sins) and there are several references that I cannot find now of religious leaders objecting to Jesus associating with women like her.
I also read an account that mentions that "Magdelene", according to tradition, likely refered to the way she wore her hair (curled). And that it refered to a style that the Talmud refers to as being a sign of a prostitute.
I think what is important is that Mary WAS a sinner before Jesus came. This much is made VERY clear. And that Jesus freed her from her sins and she became a follower of Jesus. What the exact nature of her sins WERE isn't particularly important.
Now there IS excellent record of the things Mary did AFTER Jesus' death. I don't even think the old school Catholics deny this. Mary WAS a missionary and WAS one of Jesus' closest followers as is evident by her involvement during and shortly after his death.
