Welcome Globetrotter.
I was always told attending a wedding or funeral was a matter of conscience as long as you didn't participate, so I did and was never struck dead by Jehovah.
When my non-jw mother died, I had her service at the funeral home conducted by the Episcopal priest of the church she attended. Since she was a devout Episcopalian, and totally opposed to the WT, I just couldn't bring myself to have a JW do the funeral, besides, she was well known by the priest. The priest was well aware that I was a dub, and he did a very nice job. Now that I'm out, I'm really glad I did it that way.
