Indeed you can be in a club but also in "the" family.. (point taken).. Exclusive clubs, however, tend to water down family relationships.. i.e. promote division.. Excellent take on the Mary/Martha thing.. I never saw it that way before.. Clubs can be practical but can easily overlook the obvious..
When younger I was very anti Roman Catholic but have learned that although wearing "the jacket(coat)" of some club "Martha's" can be still in "the family".. I still have a minor problem with "clubs"(all of them) not just certain ones.. But no doubt about it.. Martha's efforts were NEEDED... not by Jesus, but by other family members.. You have taken me "deeper", thanks..
I also went through a phase of having real issues getting along with the Marthas, but like you, in the end determined that the family needs the Marthas too. Ah, but the Marys! What a peaceful and joyful life they enjoy!
