Let me explain. As a Mennonite, I feel a bit of kinship with the Jewish. We are two cultures who put a lot of importance on family, food, and mothering. Singing and worship are linked. We love our grandparents. We are very aware of our history. I can't tell you how many times people have mistaken the appearance of Orthodox Jewish and Old Order Amish.
We have a lot of differences too, significant ones. Mennonite history goes back 500 years... Jewish history goes back further than I can comprehend. And let's look at the stereotypical career choices:
Mennonite = farmer
Jewish = lawyer
Of course there's the Jesus difference.
I didn't feel that it mattered, because I felt welcome there. I love that feeling. When the blessings were sung in Hebrew I got chills of the most delightful kind - ancient, full of sadness and pride and a calm confidence in the possibility of happiness.
The bride and groom are both talented and intelligent and basically amazing... and they're madly in love with each other. Weddings are awesome because they're not a finish line, they're a beginning. It's the joining of two people, two families and a new branch of history being created. I love that.
