1: Jesus meets Mary in the Garden (post-resurrection) first thing he says is " Don't cling to me!" You don't say that to someone unless touch has been part of your relationship with them. Unmarried males and females did NOT touch in that culture.
2: Mary calls him "Rabboni" which can mean both, 'My master" and 'Husband', the two terms being interchangable in the culture.
3: For Jesus to have been an unmarried 'rabbi' would have been very unusual indeed in that time and culture.
Well, ok. But this is what John 20: says: "10Then the disciples went back to their homes, 11but Mary stood outside the tomb crying. As she wept, she bent over to look into the tomb 12and saw two angels in white, seated where Jesus' body had been, one at the head and the other at the foot.
13They asked her, "Woman, why are you crying?"
"They have taken my Lord away," she said, "and I don't know where they have put him." 14At this, she turned around and saw Jesus standing there, but she did not realize that it was Jesus.
15"Woman," he said, "why are you crying? Who is it you are looking for?"
Thinking he was the gardener, she said, "Sir, if you have carried him away, tell me where you have put him, and I will get him."
16Jesus said to her, "Mary."
She turned toward him and cried out in Aramaic,
"Rabboni!" (which means Teacher).
17Jesus said, "Do not hold on to me, for I have not yet returned to the Father. Go instead to my brothers and tell them, 'I am returning to my Father and your Father, to my God and your God.' " 18Mary Magdalene went to the disciples with the news: "I have seen the Lord!" And she told them that he had said these things to her.
As far as unmarried men and women not touching, well Luke has a different take on the matter: " 36Now one of the Pharisees invited Jesus to have dinner with him, so he went to the Pharisee's house and reclined at the table.
37When a woman who had lived a sinful life in that town learned that Jesus was eating at the Pharisee's house, she brought an alabaster jar of perfume, 38and as she stood behind him at his feet weeping, she began to wet his feet with her tears. Then she wiped them with her hair, kissed them and poured perfume on them.
39When the Pharisee who had invited him saw this, he said to himself, "If this man were a prophet, he would know who is touching him and what kind of woman she is—that she is a sinner."
40Jesus answered him, "Simon, I have something to tell you."
"Tell me, teacher," he said.
41"Two men owed money to a certain moneylender. One owed him five hundred denarii,[
a] and the other fifty. 42Neither of them had the money to pay him back, so he canceled the debts of both. Now which of them will love him more?"
43Simon replied, "I suppose the one who had the bigger debt canceled."
"You have judged correctly," Jesus said.
44Then he turned toward the woman and said to Simon, "Do you see this woman? I came into your house. You did not give me any water for my feet, but she wet my feet with her tears and wiped them with her hair. 45You did not give me a kiss, but this woman, from the time I entered, has not stopped kissing my feet. 46You did not put oil on my head, but she has poured perfume on my feet. 47Therefore, I tell you, her many sins have been forgiven—for she loved much. But he who has been forgiven little loves little."
48Then Jesus said to her, "Your sins are forgiven."
49The other guests began to say among themselves, "Who is this who even forgives sins?" 50Jesus said to the woman, "Your faith has saved you; go in peace."
Finally, though true it was unusual for a Rabbi to be unmarried, it seems that Jesus did alot of things that were unusual for the time. In first century Israel(Palestine), women were considered second-class citizens, akin to slaves. The fact that they are mentioned as avid followers of Jesus is unusual – both that they would be allowed to follow him with his disciples, and unusual that the authors of Jesus’ biographies would mention their presence at all.
Apparently Jesus liked to think outside of the "box", regardless of what others thought.
