Yesterday, Benedict continued his General Audience catechesis by speaking about Ambrose of Milan. The text is here:
(I would say that while these all have been good, this one is something special. Even the beginning is a bit different, more dramatic:)

The saintly Bishop Ambrose, of whom I will speak to you today, died during the night in Milan between April 3-4, 397. It was the dawn of Holy Saturday. The day before, toward 5 p.m., he began to pray as he was lying in bed with his arms open in the form of the cross. That is how he participated in the solemn Easter triduum, in the death and resurrection of Our Lord. “We saw him moving his lips,” testified Paulinus, the faithful deacon who was invited by Augustine to write Ambrose’s biography entitled “Vita,” “but his voice could not be heard.”
Suddenly, the situation seemed to come to an end. Honoratus, bishop of Vercelli, who helped Ambrose and who slept upstairs from him, was awakened by a voice that repeated: “Get up, quick! Ambrose is approaching death.” Honoratus immediately went downstairs, Paulinus recounted, “and offered the saint the Body of the Lord. After having taken it, Ambrose surrendered his spirit, carrying with him viaticum. Thus, his soul, strengthened by virtue of that food, now enjoys the company of angels” (“Vita,” 47).
On that Good Friday of 397, the open arms of the dying Ambrose expressed his mystical participation in the death and resurrection of Our Lord. This was his last catechesis: Without speaking a word, he spoke with the testimony of life.

Speaking of evangelization:

It is evident that the personal testimony of the preacher, and the exemplarity of the Christian community, conditions the efficacy of any preaching. From this point of view a passage from St. Augustine’s “Confessions” is significant. Augustine had come to Milan as a professor of rhetoric; he was a skeptic, not a Christian. He was looking, but he wasn’t able to truly encounter the Christian truth. For the young African rhetorician, skeptical and desperate, it was not the beautiful homilies of Ambrose that converted him — despite the fact that he appreciated them immensely. Rather, it was the testimony of the bishop and the Church in Milan, which prayed and sang, united as a single body. It was a Church capable of resisting the bullying of the emperor and his mother, who had demanded again the expropriation of a Church building for Arian ceremonies in early 386.

That passage provides ample food for thought. Ample.

Dear brothers and sisters: I would like to present to you a type of “patristic icon” that, seen in the light of what we have just said, effectively represents the heart of Ambrosian doctrine. In the same book of “Confessions,” Augustine recounts his meeting with Ambrose, certainly a meeting of great importance for the history of the Church. He writes in the text that when he came to see the bishop of Milan, the latter was always surrounded by hordes of people with problems, whom he tried to help. There was always a long line of people waiting to speak to Ambrose, looking for comfort and hope. When Ambrose was not with these people — and this only happened for short periods of time — he was either filling his body with the food necessary to live, or filling his spirit with reading. In this respect Augustine praises Ambrose, because Ambrose read Scriptures with his mouth closed, and only with his eyes (cf. “Confessions,” 6,3).
In the early centuries of Christianity, reading Scripture was thought of strictly in terms of being proclaimed, and reading aloud facilitated understanding, even for the one who was reading it. The fact that Ambrose could read through the pages only with his eyes was for Augustine a singular capacity for reading and being familiar with Scripture. In this reading — in which the heart seeks to understand the word of God — this is the “icon” we are talking about. Here one can see the method of Ambrosian catechesis: Scripture itself, profoundly assimilated, suggests the content of what one must announce in order to achieve conversion of hearts.
Thus, according to the teachings of Ambrose and Augustine, catechesis is inseparable from the testimony of life. The catechist may also avail himself of what I wrote in “Introduction to Christianity” about theologians. Educators of the faith cannot run the risk of looking like some sort of clown, who is simply playing a role. Rather, using an image from Origen, a writer who was particularly appreciated by Ambrose, he should be like the beloved disciple, who rested his head on the Master’s heart and there learned how to think, speak and act. In the end, the true disciple is he who proclaims the Gospel in the most credible and effective manner.
Like John the Apostle, Bishop Ambrose, who never tired of repeating “Omnia Christus est nobis!” — Christ is everything for us! — remained an authentic witness for the Lord. With these same words, full of love for Jesus, we will conclude our catechesis: “Omnia Christus est nobis! If you want to heal a wound, he is the physician; is you burn with fever, he is the fountain; if you are oppressed by iniquity, he is justice; if you need help, he is strength; if you fear death, he is life; if you desire heaven, he is the way; if you are in darkness, he is the light. … Taste and see how good the Lord is. Blessed is the man who hopes in him!” (“De virginitate,” 16,99). We also hope in Christ. In this way we will be blessed and will live in peace.
