It is helpful to look at the verse you cited in its immediate context.
In 1 Corinthians 11:3, God states a principle regarding headship. The following three verses provide applications of that principle that are set in the worship customs of the Christians in Corinth. Then, 1 Corinthians 11:7 lists the reason for those applications: God created woman from man and for man—to be a suitable helper for him (Genesis 2:18). Woman is the glory of man in that sense.
None of this affects man’s or woman’s status before God. Genesis 1:27 states that God created Adam and Eve in his image. Being created in the image of God meant that Adam and Eve were holy, they had perfect knowledge of God’s will, and their wills were entirely aligned with God’s will. Galatians 3:26-28 declares that even though differences exist among Christians, including differences of gender, there is perfect equality among all Christians before God.
