"If you're going to be a serious student of literature, you're going to have to read the Bible cover-to-cover at least once... "
"Who made you God to say what a 'serious student' of literature should or should not read?"
" it is impossible to learn that bible as well as Brontė knew for example. She had been brought up with it and makes references to the most obscure things in it. "
Obviously Lokasenna meant "serious student of Western Literature." A working knowledge of the Bible was a given for western writers until recently, and would have been assumed for readers too.
Not all parts of the Bible would have been equally familiar. The Brontes' readers would, in good measure, have been churchgoers, hearing Sunday by Sunday portions of the Bible read out as prescribed in the Book of Common Prayer. That would make a good starting point for any serious student of English literature, at least. Those passages, the portions of the Epistles and Gospels selected for Sundays and holy days, are possibly the least dull and would certainly have been the most familiar. After that, the psalms, which were read through or sung at least once each year. Read a psalm, out loud, using the King James version, every day. Then you'll know whence come the rhythms and cadences of five hundred years of English literature.
