People say, Mary lose faith here, and just as Jesus' relatives who was there, say Jesus is mad.
But I said, no, that's not true.
The Lady who was overshadowed by God the Father and the Holy Spirit Himself (Luke 1:25), Holy Spirit work in her, she who has experienced miracles and apparition, wouldn't be like that, it's impossible for the Lady to disbelief her Son after see His miracles and wisdom, get an angelic apparition that announce her Son was the Son of God, and see the miracle of wine of her Son in the wedding party at Cana
It's impossible.
Mary is indeed there, but doesn't mean she has the same thought as the relatives of our Lord, i see that she's passive in this event.
This is what I think about this event, what actually happened.
Someone among Israelites who listen to Jesus there but not a follower of Him, seeing Him teaching, then he come to the house of the Virgin, while the relatives of our Lord was there.
He said,
"Look, your Brother teach something unclear and he's becoming a mad man, come to see Him with me."
Our Lord's relatives hearing this get mad, because they scared He's gonna wound or ruin the reputation of their family among Israelites and the people of the town, they want to preserve it, and they feeling responsible of Him since they're His relatives.
So they follow the guy that inform them.
Mary was there, sit in her house, and they look at her and ask,
"Mary, you're coming with us ?"
And she said,
"Yes, I'm coming with you all."
But she has different intention.
First, as a mother, of course she wanna go and see her Son, she's His mother.
And second, instead of think about family reputation, she's more worrying about the safety of her Son.
She's scared if people like the guy who inform them think He's mad then doing something bad to Him or His relatives threaten Him cause of it or something.
Beside, cause of the gift of the Holy Spirit, she knew clearly what happened to the Messiah, that Messiah should suffer and die, she know it'll come but she didn't know when, that made her scared all the time, if I may say, yes, paranoid.
That's why she's coming, to protect and preserve her Son from dangers that threaten Him, she's aware of her Son safety.
But yea, she still have faith and believe in Him, she wouldn't disbelief him.
They come to the house where Jesus teach and His relatives ask one of people there to call Him for them, they wanna took Him home.
It's not Mary who ask them, but His relatives, as I said before, she's passive in this.
And the guy was think like,
"Oh, his family, let's just say His mother and brethren"
"Your mother and brethren is outside, they're calling You." he say.
Mary try to find away to see Him, then she showed up at the door of the house, followed by His brethren.
Jesus looking at Mary, smile a bit to her and look at the crowd of people that listen to Him and say,
"Who is my brethren ? Who is my Mother ? It's they who do the will of my Father"
By this words, Jesus didn't aim to humiliate His mother, but praise her lowkey and confirm her divine motherhood.
It's like,
"She's My mother according to flesh, but also My mother according to spirit."
Mary heard it and just as Gospel of St Luke Chapter 2, she wonder what does it mean and she contemplate His word on her heart, but later then she understood.
But his brethren thought,
"Oh, how dare He is ?! He disrespect us and Mary ! What a rebellious and disgraceful Kid !"
It's just as St John Baptist, he also the relative of Jesus, but he didn't, nor suspected, disbelief Jesus,
instead, being one who support Him and prepare a way for His era of teaching.
He didn't suspected because He wasn't there in the place where Jesus teach at that time.
Mary is just like John, but only, she was there, so it's made misassumption that she just like His relatives, think He's mad and crazy.
