A common misinterpretation treats Paul's allegory literally as a historical reinterpretation of Genesis, diminishing the actual events with Abraham, Sarah, and Hagar, whereas Paul explicitly states it as an allegory to teach spiritual truths without negating the history; another error is using it to dismiss the Mosaic law entirely as evil rather than recognizing it as a temporary guardian that reveals sin and points to Christ, leading to antinomianism; additionally, some wrongly apply it to justify ethnic supersessionism, ignoring Paul's affirmation of God's enduring promises to Israel through faith.
Galatians 4:24
King James Version (1769)
24 Which things are an allegory: for these are the two covenants; the one from the mount Sinai, which gendereth to bondage, which is Agar.
Paul employs an allegory using Hagar and Sarah to illustrate two covenants: the one from Mount Sinai, represented by Hagar, which produces bondage and corresponds to the present Jerusalem in slavery, emphasizing the old covenant of law that cannot save but enslaves through inability to perfectly fulfill it; in contrast, it points to the new covenant of promise through faith in Christ, symbolized by Sarah and the Jerusalem above, which brings freedom and inheritance as children of God.
