I thought the same about the guys at bethel that never got married. I always thought, "So let me get this right...you don't date, you don't masturbate, you don't think about ANYTHING sexual, you only think about the organization....something doesn't sound right."
I tend to think, now, that there are probably some pretty dark secrets in some of those older guys closets that they don't want anyone to know about.
I think Macmillian was NOT married. I have a talk by him on my computer, and I can almost swear that he never got married especially after some of the things Rutherford said about marriage and children back in the day. (And by "back in the day" I mean a wednesday)
