Est Rosarium praecipue implorando Matris Dei patrocinio adversus hostes catholici nominis institutum.
Leo P.P. XIII., Salutaris ille spiritus precum, die XXIV. Decembris An. MDCCCLXXXIII.
Our Cathedral of St Michael and St Gudula is a Catholic building built by our fathers to be a House of God, for the celebration of the holy Mass, for the praise of God and the saints.
The occupation of our cathedral by Protestants to commemorate the 500th anniversary of the Reformation is therefore a profanation.
Indeed, the so-called Reformation was really a revolt: under the pretext of combatting abuses, Luther rebelled against the divine authority of the Catholic Church, denied numerous Truths of the Faith, abolished the Sacrifice of the Mass and the Sacraments, rejected the necessity of good works and the practice of Christian virtues. Finally, he attacked the veneration of the Virgin Mary and the saints, the religious life and monastic vows.
This terrible revolution was a great tragedy for Christian society and for the salvation of souls. And the Lutheran errors are still heresies today because the Truth is eternal.
