Pope Leo XIV yesterday issued In Unitate Fidei, an apostolic letter on the 1700th anniversary of the Council of Nicaea.

Pope Leo recalled the Council’s historical context, emphasized the Nicene Creed’s profession of the divinity of Christ, and reflected on its ecumenical implications today. He also spoke about the relation between the Incarnation of the Son of God and His presence in the poor today.

The Pope also discussed the continuation of the Council of Nicaea’s work at the ecumenical councils of Constantinople (381) and Chalcedon (451). He rejected the charge that the word used in the Creed to describe the divinity of Christ—homooúsios, or consubstantial—represents a hellenization of the Christian faith.

Today the Church celebrates the Memorial of St. Andrew Dung-Lac (1735-1839), priest and martyr, and companions, martyrs. St. Andrew was one of 117 people who were martyred in Vietnam between 1820 and 1862. The last of the martyrs were 17 laypersons, one of them a 9-year-old, executed in 1862.

"These women don't even see it as a sacrifice. They see service. And I see the same footsteps Christ took on the Way of the Cross."

VATICAN CITY (CNS) -- When Christians recite the Creed, it should prompt an examination of conscience about what they truly believe and what kind of example of faith in God they give to others, Pope Leo XIV wrote.

"Wars have been fought, and people have been killed, persecuted and discriminated against in the name of God," he wrote. "Instead of proclaiming a merciful God, a vengeful God has been presented who instills terror and punishes."

Publishing "In Unitate Fidei" ("In the Unity of Faith") Nov. 23, Pope Leo marked the 1,700th anniversary of the Council of Nicaea and its Creed. He said he wanted it released in anticipation of his visit to Turkey Nov. 27-30 to celebrate with Orthodox and Protestant leaders the anniversary of the Creed Christians share. 

The bishops who had gathered in Nicaea in 325 had survived anti-Christian persecution, the pope said, but were facing the fracturing of their communities over disputes regarding "the essence of the Christian faith, namely the answer to the decisive question that Jesus had asked his disciples at Caesarea Philippi: 'Who do you say that I am?'"

"Arius, a priest from Alexandria in Egypt, taught that Jesus was not truly the Son of God," the pope explained. Arius taught that "though more than a mere creature," Jesus was "an intermediate being between the inaccessible God and humanity. Moreover, there would have been a time when the Son 'did not exist.'"

The challenge facing the bishops, he said, was to affirm their faith in one God while making it clear that, as the creed now says, Jesus is "the Only Begotten Son of God, born of the Father before all ages ... true God from true God, begotten, not made, consubstantial with the Father."

The bishops, he said, knew "no mortal being can, in fact, defeat death and save us; only God can do so. He has freed us through his Son made man, so that we might be free." 

In affirming monotheism and the true humanity and divinity of Christ, the pope said, "they wanted to reaffirm that the one true God is not inaccessibly distant from us, but on the contrary has drawn near and has come to encounter us in Jesus Christ."

"This is the heart of our Christian life," Pope Leo wrote. "For this reason, we commit to follow Jesus as our master, companion, brother and friend."

The version of the Creed recited by most Catholics at Mass each Sunday and shared with other mainline Christians is formally called the Nicene-Constantinopolitan Creed, because it includes an article of faith inserted by the bishops at the First Council of Constantinople in 381 about the Holy Spirit.

Western Christians say: "I believe in the Holy Spirit, the Lord, the giver of life, who proceeds from the Father and the Son, who with the Father and the Son is adored and glorified, who has spoken through the prophets." 

A footnote in the pope's letter said that the phrase known as the "filioque" -- and proceeds from the Father and the Son -- "is not found in the text of Constantinople; it was inserted into the Latin Creed by Pope Benedict VIII in 1014 and is a subject of Orthodox-Catholic dialogue."

Recent popes, including Pope Benedict XVI, Pope Francis and Pope Leo, have omitted the phrase at ecumenical prayer services.

In his letter, Pope Leo affirmed the Catholic Church's commitment to the search for Christian unity and said, "The Nicene Creed can be the basis and reference point for this journey."

And he prayed that the Holy Spirit would come to all Christians "to revive our faith, to enkindle us with hope, to inflame us with charity."

"The Nicene Creed does not depict a distant, inaccessible and immovable God who rests in himself, but a God who is close to us and accompanies us on our journey in the world, even in the darkest places on earth," Pope Leo wrote.

Reciting the Creed, he said, should prompt Christians to "examine our conscience." 

The questions they should ask, he wrote, include: "What does God mean to me and how do I bear witness to my faith in him? Is the one and only God truly the Lord of my life, or do I have idols that I place before God and his commandments? Is God for me the living God, close to me in every situation, the Father to whom I turn with filial trust?"

And, he continued with more questions: "Is he the Creator to whom I owe everything I am and have, whose mark I can find in every creature? Am I willing to share the goods of the earth, which belong to everyone, in a just and equitable manner? How do I treat creation, the work of his hands? Do I exploit and destroy it, or do I use it with reverence and gratitude, caring for and cultivating it as the common home of humanity?"

Believing that God became human in Jesus means "that we now encounter the Lord in our brothers and sisters in need," the pope said. That is why Jesus said, "As you did it to one of the least of these brothers and sisters of mine, you did it to me."

The Creed "does not formulate a philosophical theory," Pope Leo wrote. "It professes faith in the God who redeemed us through Jesus Christ. It is about the living God who wants us to have life and to have it in abundance."
 

Gospel Excerpt, Cycle C, Mk 11:9, 10: The rulers sneered at Jesus and said, "He saved others, let him save himself if he is the chosen one, the Christ of God." Even the soldiers jeered at him. As they approached to offer him wine they called out, "If you are King of the Jews, save yourself." Above him there was an inscription that read, "This is the King of the Jews."

This feast reminds us that whatever earthly powers may do or ask of us, Christ is the true King who should reign in our hearts.

The Church celebrates the Memorial of St. Cecilia, virgin and martyr (d. 3rd century). St. Cecilia is one of the most famous and most venerated of Roman martyrs. Her body was discovered in 822 and transferred to the title church that bears her name in Trastevere in Rome. It is difficult to determine the date at which she lived. The legend which recounts the Saint's martyrdom and that of her husband St. Valerian, as also of St. Tiburtius, her brother-in-law, places her martyrdom in the pontificate of Urban I (222-230); but the authenticity of this account cannot be established, nor can we be sure of the persons who suffered with her nor of the date of her martyrdom.

Pope Leo loves his 'White Sox'! 😂

“Be intentional with your screen time. Make sure technology serves your life, not the other way around.”

VATICAN CITY (CNS) -- Pope Leo XIV urged U.S. high school students to be "intentional" with their screen time, their prayer time and their involvement in a local parish.

"One of my own personal heroes, one of my favorite saints, is St. Augustine of Hippo," the pope told 16,000 young Catholics meeting in Indianapolis. "He searched everywhere for happiness, but nothing satisfied him until he opened his heart to God. That is why he wrote, 'You have made us for yourself, O Lord, and our heart is restless until it rests in you."

With a livestream connection, Pope Leo spoke for close to an hour Nov. 21 with participants at the National Catholic Youth Conference meeting at Lucas Oil Stadium in Indianapolis.

The pope responded to questions from five high school students: Mia Smothers from the Archdiocese of Baltimore; Ezequiel Ponce from the Archdiocese of Los Angeles; Christopher Pantelakis from the Archdiocese of Las Vegas; Micah Alcisto from the Diocese of Honolulu; and Elise Wing from the Archdiocese of Dubuque, Iowa.

The questions were developed in meetings with other students and adults and were sent to the pope in advance. 

Pope Leo did respond to a question and comment posed by Katie Prejean McGrady, who was moderating the event. She mentioned that she had given the pope a pair of socks some time ago and said she wanted to know what he used as an opening word when he played Wordle each day.

"I just want to say I only wear white socks, and I use a different word for Wordle every day, so there's no set starting word," the pope said, before turning to the young people's questions.

Pantelakis asked for the pope's advice on balancing the use of smartphones and social media with "making faith connections outside of technology."

Pope Leo, using technology to address the students, listed many good things technology does. For example, "it lets us stay connected with people who are far away," he said, and there are "amazing tools for prayer, for reading the Bible, for learning more about what we believe, and it allows us to share the Gospel with people we may never meet in person."

"But even with all that, technology can never replace real, in-person relationships; simple things (like) a hug, a handshake, a smile -- all those things are essential to being human and to have those things in a real way, not through a screen," is important.

Pope Leo encouraged the students to follow the example of St. Carlo Acutis, who used technology to spread devotion to the Eucharistic but limited his time online and made sure he went to Mass, spent time in Eucharistic adoration and served the poor.

"Be intentional with your screen time," the pope told the young people. "Make sure technology serves your life and not the other way around."

Alciso asked for advice about using ChatGPT and other forms of artificial intelligence. 

While Pope Leo has continued to push AI developers and governments to formulate ethical guidelines and include controls to protect young people, he told the high school students that "safety is not only about rules; it is about education, and it is about personal responsibility. Filters and guidelines can help you, but they cannot make choices for you; only you can do that."

"Using AI responsibly means using it in ways that help you grow, never in ways that distract you from your dignity or your call to holiness," the pope said. "AI can process information quickly, but it cannot replace human intelligence -- and don't ask it to do your homework for you."

AI, he said, "will not judge between what is truly right and wrong. And it won't stand in wonder, in authentic wonder, before the beauty, the beauty of God's creation. So be prudent. Be wise. Be careful that your use of AI does not limit your true human growth."

"Use it in such a way that if it disappeared tomorrow, you would still know how to think how to create, how to act on your own, how to form authentic friendships," the pope said. And "remember, AI can never replace the unique gift that you are to the world."

Responding to Wing, who asked about the future of the church, Pope Leo told the young people they are an important part of its present. "Your voices, your ideas, your faith matter right now, and the church needs you," he said.

But, looking ahead, he asked them to ask themselves: "What can I offer the church for the future? How can I help others come to know Christ? How can I build peace and friendship around me?"

Smothers asked the pope if he ever finds it difficult to accept God's mercy.

"All of us struggle with this at times," the pope said. "The truth is that none of us is perfect."

But, he added, it also is true that God always forgives.

"We may struggle to forgive, but God's heart is different," Pope Leo told the teens. "God never stops inviting us back. We experience this mercy of God in a special way in the sacrament of reconciliation; in confession, Jesus meets us through the priest. When we honestly confess our sins and accept our penance, the priest gives absolution, and we know with certainty that we are forgiven."

"Do not focus only on your sins. Look to Jesus, trust his mercy and go to him with confidence; he will always welcome you home," the pope said to applause.
