"...the infinity of dissatisfied finiteness, but not the blessed infinity of truly limitless fullness" – "The Eternal Significance of the Humanity of Jesus for Our Relationship with God", Theological Investigations III.3

"Without him every absolute of which we speak or which we imagine we attain by mystical flight is in the last analysis merely the never attained, objective correlative of that empty and hollow, dark and despairingly self-consuming infinity which we are ourselves..."

"In brief, he was a man of prayer, a man who tasted every day the bread of death and of life, a man consumed with love for his brothers." - Preface to "Pier Giorgio Frassati: I giorni della sua vita" by Luciana Frassati

"...who has nothing sectarian about him, who lives his Christianity with a spontaneity that is almost frightening, as if he had no problems at all. In point of fact, he immersed his problems, at the price of who knows what sufferings, in the grace of his Faith."

"Here is where there appears the mysteriousness of divine grace that flies in the face of logic: in an ambient where Christianity is considered to have been overcome, there arises a Christian who breathes the joy of living..."

"His faith nourished itself with the very substance of Christianity: the existence of God, prayer as the leaven of existence, the sacraments as the food of eternal life, universal fraternity as the law of human relations."

"But what was even more surprising was that all this appeared so natural and warmly spontaneous! His faith had no human ‘explanation.’ If Frassati was Christian, it was neither in reaction to the liberal and anticlerical generation of his parents, nor because of some vague ‘cultural’ motive."

"With such basic realities of life, there is really only one alternative: either a radical protest that carried to its extreme would have to end in suicide, or an acceptance and living through of life with all its negative aspects." – "Our Relationship to the Church" in "Faith in a Wintry Season"

"What can the word 'still' mean here? It is like asking whether I will 'still' be a human being, or whether I will 'still' live in this pitiable twentieth century."

"...that the first man was also the first to incur guilt before God and his guilt as a factor of man’s existence historically brought about by man, belongs intrinsically to the situation in which the whole subsequent history of humanity unfolds." - "Hominisation"

"They do not believe in the charismatic character that belongs to the Church’s ministry even in the world of every day, even under the routine of what is laborious and unpretentious and commonplace.” — "The Charismatic Element in The Church"

"Such people may imagine they have a heroic love for the Church, of the “in spite of everything” sort. In fact, they consider themselves to possess a mind of superior discernment to that of the actual average everyday Church."

"—as though the life of the Church amounted to practically nothing but sin and falling away from the mind of Christ."

"...or if one wanted to hold with a sort of mental obstinacy (there are such people), that more or less everything is wrong that the Church has in actual practice done in the course of history, except her solemn dogmatic definitions..."

"But it would be incompatible with the invincibly Christian character and holiness of the Church and contrary to an ecclesiastical spirit to maintain that, though infallible in her teaching, she is not, in her normal life & activity, under the guidance and direction of the Spirit promised to her..."

"...can exhibit faults, omissions, partially mistaken developments, signs of sclerosis, reactionary tendencies."

"...nor does it mean that these heterodox views cannot contribute in a positive way to the further development of the Church’s understanding of the faith." — "Pluralism in Theology and the Oneness of the Church's Profession of Faith"

"...but this does not mean that such a position can be held legitimately in the Church. In rejecting a heterodox position, the Church does not rule out a person’s good faith or his chances for salvation..."

"...but the oneness of the Church’s profession, which makes her what she is, must be maintained in this complex interrelationship. We may gain some psychological, historical or sociological insight into the reasons why someone arrived at a clearly heterodox position..."
