All the women had their heads covered.
I assume this is still the practice.
I think a show of reverence for God is simply innate in humans if they are allowed to express it. It is akin to Catholics who still genuflect or kneel to receive the Eucharist rather than strictly stand in line as one would at the Dairy Queen. I applaud those women and their overt show of Faith!
I was raised Missionary Baptist, and it was an issue. If you were a child it wasn't necessary, but as an adult you better have something on your head. Didn't matter if it was a hat or a lacy handkerchief, but it better be something or the Womens Group really got ugly with each other.
