Carol:

I understand.

We can sin against God and against others simultaneously (see the prodigal's confession. I have sinned against you and God)

Of course part of the issue here was to call the community to repentance in a public way (IE, not for unbelievers but before unbelievers, before the world). Part of the issue here is to be careful that inconsistency is not a situation where God's name ends up being tarnished because of our inconsistency in the acts we perform in his name (Romans 2 discusses this). That is what the manifesto was asking for.

Hope this helps.
