“In order to save the world, Jesus Christ suffered for about thirty-six hours on the cross. I am willing to suffer an eternity in hell for the same cause.”

Context: What is the "extraordinary"? It is the love of Jesus Christ himself, love that goes to the cross in suffering obedience. It is the cross. The peculiar feature of Christian life is precisely this cross, a cross enabling Christians to go beyond the world, as it were, thereby granting them victory over the world. Suffering encountered in the love of the one who is crucified — that is the "extraordinary" in Christian existence.
The Extraordinary is without doubt that visible element over which the Father in heaven is praised. It cannot remain hidden; people must see it.

Context: The cross is not random suffering, but necessary suffering. The cross is not suffering that stems from natural existence; it is the suffering that comes from being Christian. … A Christianity that no longer took discipleship seriously remade the gospel into only the solace of cheap grace. Moreover, it drew no line between natural and Christian existence. Such a Christianity had to understand the cross as one's daily misfortune, as the predicament and anxiety of our daily life. Here it has been forgotten that the cross also means being rejected, that the cross includes the shame of suffering. Being shunned, despised, and deserted by people, as in the psalmists unending lament, is an essential feature of the suffering of the cross, which cannot be comprehended by a Christianity that is unable to differentiate between a citizen's ordinary existence and a Christian existence. The cross is suffering with Christ.

On her dark night of spiritual desolation amidst devotion, in a letter addressed to Jesus, as quoted in Mother Teresa: Come Be My Light (2007) edited by Father Brian Kolodiejchuk, p. 192; regarding this quote, Fr. Kolodiejchuk writes: "...when addressing Jesus — that is, in prayer — she could express herself with ease. Fufilling her confessor's request, she sent to him a letter addressed to Jesus, enclosing it with her letter dated September 3, 1959." https://books.google.com/books?id=P4cqT0nK_joC&pg=PA192&dq=%22when+addressing+Jesus+-+that+is,+in+prayer+-+she+could+express+herself+%22&hl=en&sa=X&ved=0ahUKEwjk0IOm5vTOAhVF1x4KHYdRDE4Q6AEIHDAA#v=onepage&q=%22when%20addressing%20Jesus%20-%20that%20is%2C%20in%20prayer%20-%20she%20could%20express%20herself%20%22&f=false

Context: My own Jesus,
They say people in hell suffer eternal pain because of the loss of God – they would go through all that suffering if they had just a little hope of possessing God. In my soul I feel just that terrible pain of loss, of God not wanting me, of God not being God, of God not really existing (Jesus, please forgive my blasphemies, I have been told to write everything). That darkness that surrounds me on all sides. I can’t lift my soul to God – no light or inspiration enters my soul. I speak of love for souls, of tender love for God, words pass through my words sic, lips], and I long with a deep longing to believe in them! What do I labour for? If there be no God—there can be no soul.—If there is no soul then Jesus—You also are not true... Jesus don't let my soul be deceived—nor let me deceive anyone. In the call You said that I would have to suffer much.—Ten years—my Jesus, You have done to me according to Your will—and Jesus hear my prayer—if this pleases You—if my pain and suffering—my darkness and separation gives You a drop of consolation—my own Jesus, do with me as You wish—as long as You wish, without a single glance at my feelings and pain... I beg of You only one thing—please do not take the trouble to return soon.—I am ready to wait for You for all eternity.

Context: Jesus Christ has to suffer and be rejected. … Suffering and being rejected are not the same. Even in his suffering Jesus could have been the celebrated Christ. Indeed, the entire compassion and admiration of the world could focus on the suffering. Looked upon as something tragic, the suffering could in itself convey its own value, its own honor and dignity. But Jesus is the Christ who was rejected in his suffering. Rejection removed all dignity and honor from his suffering. It had to be dishonorable suffering. Suffering and rejection express in summary form the cross of Jesus. Death on the cross means to suffer and to die as one rejected and cast out. It was by divine necessity that Jesus had to suffer and be rejected. Any attempt to hinder what is necessary is satanic. Even, or especially, if such an attempt comes from the circle of disciples, because it intends to prevent Christ from being Christ. The fact that it is Peter, the rock of the church, who makes himself guilty doing this just after he has confessed Jesus to be the Christ and has been commissioned by Christ, shows that from its very beginning the church has taken offense at the suffering of Christ. It does not want that kind of Lord, and as Christ's church it does not want to be forced to accept the law of suffering from its Lord.

The Plan of Delano (1965)
Context: We are suffering. We have suffered, and we are not afraid to suffer in order to win our cause. We have suffered unnumbered ills and crimes in the name of the Law of the Land. Our men, women, and children have suffered not only the basic brutality of stoop labor, and the most obvious injustices of the system; they have also suffered the desperation of knowing that the system caters to the greed of callous men and not to our needs. Now we will suffer for the purpose of ending the poverty, the misery, and the injustice, with the hope that our children will not be exploited as we have been. They have imposed hunger on us, and now we hunger for justice. We draw our strength from the very despair in which we have been forced to live. We shall endure.
