Many Protestant denominations teach that God's law is done away. Earl Henn proves that II Corinthians 3:7 does not support this.
John Ritenbaugh asserts that the Old Covenant in no way annulled the promises of the Abrahamic Covenant, but was added because of Israel's sins, with the intent of pointing to the need of a Savior. Because the primary focus of Galatians is justification rather than sanctification, the Protestant antinomian bias looks quite foolish and stupid. The New Covenant, grafting the Law into the recesses of the heart (Hebrews 8:10; 10:16) in no way does away with any aspect of the law. The deficit in the Old Covenant was in its lack of a means of justification (forgiveness of past sins). The New Covenant, having a means of justification, replaces the pre-figuring symbolic animal sacrifices with the perfect sacrifice of the Messiah. Circumcision of the heart and the receipt of God's Holy Spirit ratifies the New Covenant.
John Ritenbaugh reiterates that the entire Old Testament was written with the New Testament church in mind. Certain temporary ceremonial sacrifices, washings, and rituals were set aside when the spiritual reality—such as Christ's sacrifice replacing animal sacrifices and God's Holy Spirit and His Word replacing physical washings (Hebrews 9:18; Ephesians 5:26)—added a spiritual dimension. All biblical law, including the ceremonies, comes from God. Paul never taught any Jew to forsake the Law of Moses, the constitution and civil code, but he did rail against Pharisaical additions for the expressed purpose of attaining justification. Even though a change occurred in the administration of existing law, no laws were done away. Instead, they are written in the hearts of the converted (Hebrews 8:10; 10:16).
