When you have one preposition and two objects, the writer is telling you, in a very nuanced way, that you should be viewing the two objects as a single entity. Not identical, but in some way functioning as one. So when a single preposition governs both "God" and "Christ," what is Paul saying?
What does a preposition with two objects tell us about the divinity of Jesus? (1 Tim 1:1)
