Few texts if any have had as wide an impact influencing moral thought patterns as has the one brief word of Jesus, Matthew 5:28, in which the lustful regard is equated with adultery. But just what is the lustful regard and what is not? As is often the case with very familiar phrases, definition is not as easy as many assume. The following text argues that because of a far-reaching misunderstandingof sexuality in general, which also influences the most frequent interpretation of this passage, what Jesus meant and did about sexuality is not grasped correctly. If Jesus were correctly understood, this passage in particular could be "liberated" from its usual guilt-producing meaning and could be seen to be teaching something very different.
