In the Sermon on the Mount we have the most complete biblical exposition of Christian nonduality. It is not the type of description of nonduality that one would hear today. It does not talk about consciousness. It does not present a monistic or panentheistic understanding of reality. Jesus speaks of how oneness with God and all things is expressed in behavior. Among other things he says it is expressed by loving our enemies. 

Nonduality is most clearly represented in the Old Testament with the biblical word shalom. The word is normally translated “peace” but shalom is not the absence of conflict. It is present no matter the circumstances.
