Wrong question.
Yes or no, Caww?
You said that all protestants are in union with one another.
Bishop Vicky Gene Robinson is a protestant
You are a protestant.
Therefore, I can only conclude that you are in unity with him.
IF you are not in unity with him - how does one determine which protestants are in unity with one another since you are saying that not all of you are in union with one another despite both of you calling the other, ‘protestant’.
