I disturbed the conscience of the elder body when I would call on members of the congregation by their first names when I had parts at the meetings or when conducting the book/bible study.
For example, Brother James, Sister Janice, Brother Richard, Sister Samantha... (iso using their family names, Brother Smith, Sister Jackson).
They couldn't use the Bible to any satisfaction for their rebuttal, but only some articles from the Talmud Watchtower as their authority.
