there is a slowly growing tendency of Lutherans to cross themselves on the speaking of the triune name (F, S, HS) This gesture has never stuck with me. You will note in the video that at the end of the prayer that the woman directly in front of the camera is also "old skool" in that regard--her hands actually kind of go to her pockets! She's the wife of the co-instructor, herself a formidable pastoral caregiver.
