If he had converted to xtianity would that be a betrayal of his family? Perhaps she is not being manipulated but really believes in converting.

Is she not going to be welcome if she converts? Will she be "cast out" if she converts?

Why not let her make her own decision. I assume she is old enough to decide for herself.

"Jesus is the only G-d" Umm....wow. JUST WOW!

Maybe she actually looked at xtianity with an open mind and decided it was not something she believed in and in fact was contradictory to Torah so she went where her heart led her. Maybe you should ask her WHY she converted and then listen to what she has to say. If she says her boyfriend made her, then ok, she is being manipulated but if she answers with her own mouth in her own words, then she has simply found another belief system that she can embrace.

why are you so worried about her converting to judaism she will still be your sister, you may find that you need to do things differently for example you may not be able to cook for her due to the kosher food rules so you will have to go round to her house for dinner or let her do it, which you may actually enjoy.

you may even find that she changes or improves for the better or in a good way.

in the unlikely event that she goes to religious to the point that you cant get along or see eye to eye then live and let live these things sometimes happen

i am not jewish but common sense should tell you what i have told you

I am sorry, I am on your sister's side. My family disowned me for changing Christian denominations, so I have a great deal of sympathy for yous sister. If she is that convinced of her believes, then you should support her instead of being such a stiff neck.

The same Christians have been converting people for centuries

Through fear and violence

C'mon you say you're a Christian, you should have thousands of references in your scriptures

And history

I personally think that Jews make a damn good argument that Jesus did not fufill the requirements of the Messiah. If I had to worship YHWH or die I'd be a Jew. Let her be... if she's old enough to get married, she's old enough to choose what she's doing with her life.

"She met a Jewish guy and she will convert to his religion"

wow...that was easy, huh? maybe I'll meet a hindu girl and I'll magically see how that religion is evident or logical in any way at all like your sister does with judaism

Your best bet is to back out gracefully it is your sister's choice. There damn sure isn't anything special about being a "Christian family".

So basically you're saying only YOU have the right to manipulate her?

Let it go. If she wants to believe in a different sky magicians than you, let her do it. What's the harm? You both don't make sense in the first place.

Jesus was a Jew. If it was good enough for Him...
