One of the things we noticed at yesterday's fraternal was the irony, or sarcasm, of the writer in 2 Samuel 11:4 (now she [Bathsheba] had purified herself from her uncleanness.'
Bathsheba is on her way to commit adultery, and she knows it. David has sent for her in order to commit adultery, and he knows it. But - hey! What's the moral law anyway? Provided the ceremonial law - the 'incidentals' of religion - are being observed...
One Christian lady whose husband has left her for another woman told me recently that he had told her 'I know what we're doing is wrong. But we are reading the Bible and praying together.' OK; that's all right then.
Jesus called it straining at a gnat and swallowing a camel.
