Run Away Home / Religion

[slemslempike.livejournal.com]

Inquiring minds want to know. I was rereading Run Away Home, and I have a few religious-related questions. I'm an atheist, albeit with a vaguely Protestant background, and I don't understand some of the terms. Rowan says that when Ramsay does his duty by the ASB, Mrs Marlow goes to Evensong instead of Matins. So:

1) What's the ASB?
2) What's Evensong? Given the context, is it a Catholic service?
3) Why does Mrs Marlow cut Matins when it's the ASB?
4) Why does this upset Ann?
