Our Lady of Akita:

The work of the devil will infiltrate even into the Church in such a way that one will see cardinals opposing cardinals, bishops against bishops. The priests who venerate me will be scorned and opposed by their confreres … churches and altars sacked; the Church will be full of those who accept compromises and the demon will press many priests and consecrated souls to leave the service of the Lord (Message of Oct. 13, 1973).

… If men do not repent and better themselves, the Father will inflict a terrible punishment on all humanity. It will be a punishment greater than the deluge, such as one never seen before. Fire will fall from the sky and will wipe out a great part of humanity, the good as well as the bad, sparing neither priests nor faithful. The survivors will find themselves so desolate that they will envy the dead. …

The only arms which will remain for you will be the Rosary and the Sign left by My Son. Each day recite the prayers of the Rosary. With the Rosary, pray for the Pope, the bishops and priests. The demon will be especially implacable against souls consecrated to God. The thought of the loss of so many souls is the cause of my sadness. If sins increase in number and gravity, there will be no longer pardon for them…

Our Lady of Fatima:

[T]he final battle between the Lord and the reign of Satan will be about marriage and the family. Don’t be afraid, she added, because anyone who operates for the sanctity of marriage and the family will always be contended and opposed in every way, because this is the decisive issue. And then she concluded: however, Our Lady has already crushed its head. (Final message to Sr. Lucia, 1981).

Pope Benedict XVI on Fatima:

… In 2000, in my presentation, I said that an apparition – a supernatural impulse which does not come purely from a person’s imagination but really from the Virgin Mary, from the supernatural – that such an impulse enters into a subject and is expressed according to the capacities of that subject. … Consequently, I would say that, here too, beyond this great vision of the suffering of the Pope, which we can in the first place refer to Pope John Paul II, an indication is given of realities involving the future of the Church, which are gradually taking shape and becoming evident. So it is true that, in addition to [the] moment indicated in the vision, there is mention of, there is seen, the need for a passion of the Church, which naturally is reflected in the person of the Pope, yet the Pope stands for the Church and thus it is sufferings of the Church that are announced. The Lord told us that the Church would constantly be suffering, in different ways, until the end of the world. … As for the new things which we can find in this message today, there is also the fact that attacks on the Pope and the Church come not only from without, but the sufferings of the Church come precisely from within the Church, from the sin existing within the Church. This too is something that we have always known, but today we are seeing it in a really terrifying way: that the greatest persecution of the Church comes not from her enemies without, but arises from sin within the Church, and that the Church thus has a deep need to relearn penance, to accept purification, to learn forgiveness on the one hand, but also the need for justice. Forgiveness does not replace justice.

Sr. Lucia, Interview in 1957:

That which afflicts the Immaculate Heart of Mary and the Heart of Jesus is the fall of religious and priestly souls. The devil knows that religious and priests who fall away from their beautiful vocation drag numerous souls to hell. … The devil wishes to take possession of consecrated souls. He tries to corrupt them in order to lull to sleep the souls of laypeople and thereby lead them to final impenitence. He employs all tricks, even going so far as to suggest the delay of entrance into religious life. Resulting from this is the sterility of the interior life, and among the laypeople, coldness (lack of enthusiasm) regarding the subject of renouncing pleasures and the total dedication of themselves to God.
