"Mary is the Queen of heaven and earth and our Queen because she is the Mother of our Lord and because she cooperated in Christ's redemptive work of salvation. Since she was uniquely associated with Christ's suffering on the Cross, she was uniquely associated with His triumph and royal reign in the kingdom. Assumed into heaven, Mary entered the royal court of heaven and sits at the right hand of her Son, Christ the King. As our Queen, Mary directs us, protects us and intercedes for us."
