In his sermon titled 'Clip: Bad Hermeneutics Warning,' David Green uses an illustration to warn against improper interpretation of biblical texts. He recounts an example often used by his grandfather, where one could mistakenly combine two separate Bible passages—'Judas went out and hung himself' and 'go thou and do likewise'—to form a flawed doctrine. This serves as a warning about bad hermeneutics, emphasizing the importance of understanding scripture in its correct context and avoiding the fusion of unrelated passages to derive theological conclusions.
My grandfather used to give this illustration all the time. Maybe you've heard it before. It's in a, I've seen it in a couple books. But if you read in one passage in your daily Bible reading, The Judas went out and hung himself. He said, oh, yeah, that must be true.
And then you remember that you read somewhere else that the word says, go thou and do likewise. That would be a very bad hermeneutic to squish those two together and make a doctrine out of it.
