Lots of good stuff there. In addition to the main point on divinity, there are peripheral points of interest such as:
- Metrodorus having a child, which bears on the marriage / children issues.
- The advice to be obedient to parents, which might be relevant to issues of reverence / respect for teachers.
- The reference to slaves, which bears on attitudes towards individual slaves as well as slavery itself (probably one of the best examples for remembering how morality is relative to circumstances)
- I gather at least part of one letter is directed to a young person (?) which would bear on how Epicurean philosophy is something to teach young people and not just for adults.
