OK, here’s the starter post. Since this wasn’t originally my question, I’ll just play host and yield to David if he wants to reframe what I put here.
I think the question (although specific in the original to birth control) was beginning to broaden out to encompass all actions, so I’ll try to phrase this a couple of different ways as I understand it.
How shall we define action in relation to sin? Are sins only actions, or may motives also be sins? This references a deeper question: what is sin exatly? Given any particular action/motive, how do we figure out if it’s sin or not? Are there grey things? How do we figure those out?
All right. Game’s in play.
