If the three share one name then what is this name? Chapter and verse please. Luke 9:26 speaks in a similar way when literally translated, speaking of the glory of Christ, and of the Father, and of the holy angels. Does that mean that the Father's glory is no different from the glory of angels? Or could it be that we ought to recognise ways of speaking (that we even use today) instead of grasping for proof texts? And shouldn't we also be open to the idea that a name or authority can be shared between three ontologically different parties?
