I’ve read a brain study that suggested that clans or family tribes were how we were designed to live. Our neurological pathways show that humans are most sociable and psychologically healthy when we are living in groups of around 150 people or so.
Yes.
So for those without large blood families the best thing is to become deeply embedded with a small to medium sized faith community who truly become one’s “extended family”.
IOW “megachurches” will generally not fill that void.
