Yes, it would be the biggest mistake to leave the Church, because the Church is our mother. How can you leave your mother? The Church gave us supernatural life, not the Pope, not the bishop, but the Holy Mother Church. We say this to the people: the Church is greater than the Pope, the bishop, or the cardinals. They are only members of the Church, too. So the Church is greater.
Therefore, we must love our Mother Church, especially now, in this time of her passion. We have to tell people that our Mother Church is now enduring Holy Friday. Because the Church is the Mystical Body of Christ, by divine permission, God has allowed the Church, in the past 50 or 60 years, to enter truly into the way of the Cross, the Stations of the Cross.
I believe now, in our current time, we have arrived at Calvary, Golgotha. Our Mother Church is humiliated as Jesus Christ was. She is in chains, as Jesus was tied. And today, those who humiliate our Mother Church are not mainly the external enemies, but, astonishingly, the clergy, mostly even high clergy within the Church.
This is a mystery, in some way like Judas, which God also permitted for His purposes. So we must remain with our Mother Church and say: We will be with you in this time of Calvary. We must be faithful to our Mother Church by keeping the immutable faith we know.
Why would anyone want to leave the Church? It makes no sense. These people have the faith. They know the Catechism. They know the saints. They can receive Holy Communion, even if they must travel some distance to find a worthy, holy Mass. Many Christians have done this and still do so during times of persecution.
What they lack is the understanding that it is a mistake to identify a concrete holder of an ecclesiastical office, even if it is the Pope or a bishop, as the totality of the Church. This is the error we must abandon. The Church is larger and greater than any one person.
So we must encourage the faithful to stay with our Mother Church. Of course, you have the right to resist heresy, even if it comes from your bishop or the Pope, but it must be done respectfully, not like people without faith or as if we are members of some worldly party fighting battles.
We are members of the Mystical Body of Christ, and the Church is ultimately a supernatural reality, not just an organization. Therefore, we must use other means, not those of worldly factions or parties, which are like wars.
We must be faithful to the Church’s teaching, pray faithfully, and prepare ourselves for the infidelity and apostasy of, unfortunately, some shepherds of the Church.
