Leviticus 18 talks about sexual morality, whereas Leviticus 19 talks about food and what to eat and what not to eat. It is quite difficult to read these two passages together. Modern Christians seem to obey the sexuality commands in chapter 18, but not 19. But if we really believe in Bible is the word of God, we need to read them consistently, not intepreting one chapter according to one set of rules and another, another set of rules.
How should we interpret Leviticus 18 and 19? Should we obey both? Or should we obey none? If we obey only chapter 18, but not 19, what is the hermeneutical ground for this?
