We received a letter from children's school that ethics classes were about to start for children who didn't attend scripture lessons.
Not a bad idea; I hope they start with ethical epistemology and the naturalistic fallacy just to get things straight. That is, on what basis can ethical judgements be made in a materialist world that don't descend either to the convenience of the individual, or the will of the powerful. If you think that 'community agreement' is a valid basis, then you are voting for the will of the powerful, and that can change at a moment's notice.
The other problem with 'ethics' is I wonder where forgiveness is located. In a Christian ethical framework I know where to find it, but what if you make ethical mistakes, or cannot keep up with your own ethics? Does this leave a child with an unsolvable dilemma?
