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!
And I agree whole-heartedly. I was just amazed to see it, though I've never seen it since in any other Protestant denominational church.
