So my S.O. just informed me she may be joining a fundy church

45. First of all, they do study those things

Second, the sermon on the mount isn't the win you think it is:

As a whole, the Sermon on the Mount is, to put it bluntly, a bad sermon. Beyond giving some bad advice, it doesn't have any underlying theme. It is a hodgepodge of bottled wisdom. No section leads into another section, and often the advice within the sections are contradictory.

As but one example of how bad it is as a moral guide:

And if thy right eye offend thee, pluck it out, and cast it from thee: for it is profitable for thee that one of thy members should perish, and not that thy whole body should be cast into hell. 30And if thy right hand offend thee, cut it off, and cast it from thee: for it is profitable for thee that one of thy members should perish, and not that thy whole body should be cast into hell.

Taken literally this is stupid advice. Taken figuratively, it's still bad advice. Essentially, he's saying that it is wise to deny your nature instead of working to understand it, change it or channel it into productive, positive results.

And that's only the beginning of how much of a fail it is.
