The kingship of Jesus Christ and the queenship of the Blessed Virgin are not two unrelated things. The queenship of Mary is nothing other than a means–or rather the means–for the realization of the kingship of Christ.
The Heart of Jesus reigns and triumphs in the reign and the triumph of the Heart of Mary. The reign and the triumph of the Heart of Mary consists in nothing other than having the Heart of Jesus reign and triumph. And so, these two great torrents of devotion that sprang up shortly after protestantism advance toward the same goal, for the preparation of the same event: the reign of Jesus and of Mary, in a new historic era.
