A bit of personal backstory... some years ago I heard of a dad who received a terminal illness diagnosis. To care for his daughter into the future he would not be around for, he created a Council of Dads. Inviting individuals from his life network to serve on this council as "the go to guy" when a problem or issue arose that his daughter needed a Dad's advice.
Impressive concept. As I was slipping into my elder years, I realized that I needed a council of women, women who might guide or mentor me into a season of life for which examples of women bearing witness were scarce. 

I mention because a woman can form her own council of women, without pressing for the universally accepted and acclaimed qualification OR limited to Christian, single, married etc.  What I discovered is we don't even think of the 'elder' years of women.
Mary, Mother of Jesus.... 14 ish at birth plus 30 has Mary at 44 at the beginning of his public ministry + 3 that's 47. Now, she's on my council -- 

Try it?
