Iris, I apologize for responding to you; it could be to anyone. If your innuendo about Mahony were true, what would that say to you? Where is a sense of Christ's love for his children in this discourse? What does your religion really mean to you? How do your objections advance Christ's message of love over law?
Reading the Gospels there is no doubt that Jesus saw the books of the law, the books of Moses, as the unerring word of God. To ignore the Books of the Law, to see them as not the word of God, is an old heresy, Paulicianism, Catharism, later, Bogomilism.
To imitate Christ we must take Leviticus 20 as seriously as Exodus 20.
