Having abolished in his flesh the enmity, even the law of commandments contained in ordinances; for to make in himself of twain one new man, so making peace; Having abolished in his flesh - By his incarnation and death he not only made an atonement for sin, but he appointed the doctrine of reconciliation to God, and of love to each other, to be preached in all nations; and thus glory was brought to God in the highest, and on earth, peace and good will were diffused among men.
The enmity of which the apostle speaks was reciprocal among the Jews and Gentiles. The former detested the Gentiles, and could hardly allow them the denomination of men; the latter had the Jews in the most sovereign contempt, because of the peculiarity of their religious rites and ceremonies, which were different from those of all the other nations of the earth.
The law of commandments - Contained in, or rather concerning, ordinances; which law was made merely for the purpose of keeping the Jews a distinct people, and pointing out the Son of God till he should come. When, therefore, the end of its institution was answered, it was no longer necessary; and Christ by his death abolished it.
To make in himself - To make one Church out of both people, which should be considered the body of which Jesus Christ is the head. Thus he makes one new man - one new Church; and thus he makes and establishes peace. I think the apostle still alludes to the peace-offering, שלום shalom, among the Jews. They have a saying, Sephra, fol. 121: Whosoever offers a peace-offering sacrifice, brings peace to the world. Such a peace-offering was the death of Christ, and by it peace is restored to the earth.
