I've known the people involved in this for quite a while. I think the elder, who knows the husband well, was not quite sure how to handle the situation. He seemed a little uneasy about things and messed up big time reading the scripture from Job (couldn't find the exact verse in his notes after he drew attention to the words of the "prophet" Job). He came across as very unprepared as he messed up naming the family (he was reminded at the end of the talk by a daughter before his prayer) and stumbled through the eulogy prepared by the family as if he had never seen it before.
It was definitely an unusual situation, which I can understand. But the "god bless you" comment really stunned me. There was really no need for him to say that. Of course, it also stunned me when the theme of the DC a few years ago was "Follow the Christ" and also when I walked into a recently remodeled KH less than a year ago and was faced with a big picture of Jesus with his outstreched hand in the entryway. Having been a JW since my birth more than half a century ago these things catch my attention, they just aren't things JW's do.
