Christ said during His Sermon on the Mount that He did not come to destroy the Law or the prophets but to fulfill them (Matthew 5:17).
The fourth commandment is to honor thy father and mother. The mother of Christ was Mary (Luke 2:7). Therefore, Christ honored His mother. When He was found in the Temple at the age of twelve, Scripture records that He submitted Himself to his parents (Luke 2:51).
If Christ honors His mother and submits Himself to her, and if we are Christ’s disciples (which means His followers), we must emulate Christ, which means we too must honor Mary.
Furthermore, Christ was exalted because of His humility, for God exalts the humble.
Have this mind among yourselves, which was in Christ Jesus, who, though he was in the form of God, did not count equality with God a thing to be grasped, but emptied himself, taking the form of a servant, being born in the likeness of men. And being found in human form he humbled himself and became obedient unto death, even death on a cross. Therefore God has highly exalted him and bestowed on him the name which is above every name, that at the name of Jesus every knee should bow, in heaven and on earth and under the earth, and every tongue confess that Jesus Christ is Lord, to the glory of God the Father. – Philippians 2:5-11
If Mary, who out of love for her son, lived the same spirit of life (poverty, suffering, obedience until death), then God has exalted her as well to a rank just after God in the supernatural order (the “order of grace”)1. It can be said then that, after Jesus, her name, Mary, is the name above every other name and every one must confess that she is the Mother of God to the glory of God the Son.
