1 and 3 are both references, I don't plan on reading Josephus' one from beginning to end, but own it in order to check sources and quotes. I'll need Jewish Antiquites too, but it wasn't there.
2 is, basically, going to be used as compendium of references to evil, Mara, etc, in various Buddhist and Christian texts.
I've read most of 4 already. Bahai is a very bad religion in terms of human welfare, having many of the same teachings on marriage, sex, etc, that Abrahamic religions have, and is Islamic in nature, but more liberal. Bahai appeals to some Muslims, so represents a religion that may be capable of making Islamic countries more liberal and less monstrous.
