1. In Greek the vocative is the case of address. 2. In question here is the vocative adelphoi, "brother" or "brothers and sisters." 3. So when Paul addresses the Galatians with the fimiliar vocative adelphoi: a. Is he addressing only the "brothers," b. Or is he addressing both "brothers and sisters"? 3. Last month I visited one of the founding members of the church I pastor. She's 94; her body is failing her, but her mind is as sharp as can be. While visiting with her, she said to me thinks and prays for her "brothers and sisters" in the Lord.
