Hi Quotes:
When she says "My hands are tied", it makes me think back to my own wedding. My best friend was very disappointed that I didn't invite her to be my maid of honour, and the only reason I couldn't was because she was not baptized (raised a JW and her father was the PO in my home congregation). The elders in the congregation where we lived had basically told us that if she was not baptized, then we couldn't use the KH for the wedding and the brother doing the ceremony would not marry us. It was blackmail, pure and simple.
The same body of elders, 7 months later, allowed my husband's brother to get married there, with his newly baptized (2 weeks!) fiancee's worldly sister acting as maid of honour. Because the sister had never set foot in the KH before, and there were going to be worldly relatives at the wedding who might potentially start studying etc, they allowed this to take place.
In my case, allowing an unbaptized person to stand for me might have "stumbled" some "weaker" ones. In my sister-in-law's case, it opened the way for sharing The Truth™ with others. The decision is made solely for appearances' sake. I think it rather odd that your sister would invite your wife (I get the impression that your wife is a JW in good standing, otherwise, for appearances' sake you would both be invited, so as not to potentially offend a non-JW) and say she has to decide for herself whether to attend.
I think maybe the elders may have put some pressure on your sister, the same way they did to me. However, she does want you at the wedding, and to be in the photographs. She has not said that she does not want you at the reception, she has said that she "can't invite you". Maybe she's hinting that you should just show up anyway?? What would a wedding be if there was no photograph of the bride dancing with her brother??
I would understandably be hurt. I felt just awful when I had to tell my friend why she couldn't be my maid of honour, and felt even worse when her whole family refused to attend my wedding because of it.
This kind of nonsense shows how unchristian JWs can be, when this is supposed to be a day of happiness for two people in love.
