Have attended a Bible study at Laguna Del Sol and a church service at Glen Eden (both many years ago).
All home Bible study is done nude, because we are created in His image, why hide it? Only satan is offended by God's image, and those who are under satan's influence will toe the line and act all offended by nudity. Even so-called Christians get offended by nudity because they still follow satan. Yes, satan finds the image of God offensive. What a shock.
So, with that in mind, why should it matter if you are nude when worshiping or studying the word of God? No big deal. Unless you are satan.
