… that ain’t necessarily so.
Here is a list of 76 things that the book of Leviticus bans, many of which are punishable by death. It is nice to have all in one place to use as rejoinders to those who obsess about just one on the list (#39) and ignore all the others.
Reading the list, you realize immediately how Leviticus, like the rest of the Bible and other holy books, were written by humans who reflected the thinking of their times, which are pretty silly when viewed in a modern light. It beats me how anyone can think that this rubbish was divinely inspired work that represent timeless truths.
If you leave aside all those whom you should not have sex with (and there are a lot) there are only a handful (5, 6, 9, 10, 38, 44, 45, 47-53, 63, 66, 67, 74, 76) that would be even debatable as moral issues these days.
