And if you look at the particular Greek word that was translated into "fulfilled" (kataluo), it is typically used in context such as "to overthrow", "to render vain", etc. The purpose of the Law of Moses was to provide a simpler law that was to be "fulfilled" (i.e. rendered out of date) with Christ's coming. This is why Christians typically do not practice circumcision, burnt offerings, the scapegoat ritual, etc. All of those were a facsimile for the Messiah and are now obsolete as Christ has already been born, performed his mortal ministry, suffered in the garden, and was crucified.
