Paul mentions he 'wrote briefly' about this. Why is this seemingly small detail important for how we approach Scripture?
The parenthetical phrase 'as I have written briefly' is more than just a literary aside; it's a key to understanding Paul's method and the nature of his letter.
Reference to Prior Teaching
Commentators suggest Paul is referring to earlier sections within Ephesians itself, likely chapters 1 and 2, where he has already touched upon aspects of this mystery. This indicates that the readers already have some foundational understanding, and Paul is now elaborating further.
Building on the Word
This also shows that Paul didn't introduce entirely new concepts without grounding them. He built upon what he had already established, demonstrating a logical flow in his teaching. The repetition or reference reinforces the importance of the message and encourages the readers to connect the dots within Scripture.
Encouragement to Study
It invites us, as readers, to do the same: to look back at what has been written, to see how the pieces fit together, and to recognize that God's Word is a coherent message meant to be studied and understood.
