How do the Ten Commandments relate to Christians? Against the moral/civil/ceremonial law division

Winger rejects the traditional threefold division of the law (moral/civil/ceremonial) as convenient but potentially misleading — it suggests Christians are bound by the moral part but not others, when actually we are not positionally under any of it. Instead, he looks to Christ's character and teachings, and uses OT law as wisdom and instruction informed by NT interpretation.
