In communion with the suffering Catholics in Spain, which we have seen above, Eugene wrote a pastoral letter to his diocese.
Yes, my dearly beloved brethren, you cannot merely watch without taking interest in the sad situation. A portion of what used to be one of the most flourishing parts of Christianity stands to be violently torn from its ancient spiritual foundations and so be separated from God’s Church. How can we not be terrified at this schism which would come about in the name of a temporal power taking upon itself the right to be like a wall of separation between the bishops and the Vicar of Christ, between the faithful and him who is their common Father? …There is no law that can go against the law of God, no constituted power whatever, that can supersede the divine constitution of the Church.
Bishop Eugene de Mazenod, Pastoral Letter to the Diocese of Marseilles 1842 (Rey)
To this purpose he organized prayer services in Marseilles.
First station for the Jubilee at the cathedral. The church was found to be much too small: two hours before the designated time, the three naves and all the chapels were full. They arrived in droves to assist in this holy action. The doors had to be closed.
This glorious gathering was a magnificent spectacle, made up of the principal pastor, surrounded by all his clergy and a multitude of the faithful, in order to solemnly invoke the Lord in favor of a part of the grand Christian family threatened in its faith. I intoned the Veni Creator, which was sung by thousands of voices, inspired, as I was myself, by a living sense of fraternal charity, of filial trust, and by a certain, inexpressible interior jubilation. This joy stemmed from the grand communion of saints, whose perceptible impression it was impossible not to experience, with the joy of sensing that one belongs to this Catholic Church, which has God for Father and all baptized persons as brothers and sisters.
