Deuteronomy

The amazing achievement of this book is that it attempts to set out a procedure for fair trials among a wandering desert people in early, pre-literate age. The problem is that the all-merciful God proceeds to sanction multiple genocides, sex slavery, death by stoning for various trivial offences, eternal damnation for eunuchs, and, somewhat superfluously, an outright ban on sleeping with one's mother-in-law.

Barking bloody mad, and all the more entertaining for it - just so long as nobody takes any of this nonsense seriously, right?.
