I assert that from a Christian and Judaic convention around the first century and prior all sins are social sins.

Is it possible then, for someone to sin alone?

Matthew 5:28 - But I tell you that anyone who looks at a woman lustfully has already committed adultery with her in his heart.


Also, if you take Matthew 25:31-46 and Luke 10:30-35. These sins are sins of inaction. So, it depends on what you mean by committing a sin alone.

I'm just trying to get a better understanding of what you mean by 'alone'? Are you speaking in the theoretical terms of 'if you were the onyl person alive, could you sin?' or in the terms of 'if you're in your bedroom alone, could you sin?'

Alright, what's the definition of sin? Are you referring to sins under the new covenant or the old one?

If you are referring to the old covenant, then I would say yes, you can sin. For my argument I take the first four commandments from exodus 20. None of them have any direct social implications but are totally based upon the relationship between man, or a man, and God.

If you are referring to the new covenant, then I'm not sure. Matthew 22:34 would hint that you can sin in isolation, but then you would have to make the argument that loving God is independent of other people. Also, most of the teachings of Jesus were relational. Matthew 12:32 is the only verse I can think of that doesn't necessarily require other people in existence.
