(but) not in the biblical sense

Not in a sexual way. Usually used in reference to the word "know," which, in the Bible, often indicates a sexual relationship between two people. A: "I hear that you know Liz." B: "Not in the biblical sense, if that's what you're hinting at!" Yeah, I know Callie, but not in the biblical sense—we used to be neighbors, that's all. The senator says he knows that woman, but not in the biblical sense. Anyone else skeptical, or is it just me?
