(Spanish translation below) "Today, on the solemnity of the Most Holy Trinity, Bishop John E. Keehner promulgated his first pastoral letter, Sic Deus Dilexit Mundum: God So Loved the World, a pastoral reflection on the meaning of the Sacred Heart of Jesus for Our World Today.

"The letter was authored ahead of the June 11, 2026 consecration of the nation to the Most Sacred Heart of Jesus as the United States celebrates the 250th anniversary of the signing of the Declaration of Independence."

This Sunday is known as Trinity Sunday, and our readings invite us to think about God as Father, Son, and Holy Spirit. The readings present a God who is kind, patient, and caring. God speaks to Moses with mercy. Paul calls people to live in peace. These words remind us that God stays close to His people.

The Gospel tells us God loves the world, so He sent His only Son to redeem us. Faith in the Son opens the door to new life. The Holy Spirit helps us grow in holiness and stay united to the Father and the Son. This Sunday calls us to trust God, live in peace, and share His love with others.

Monday, May 25th, Pope Leo released his first Encyclical titled “Magnifica Humanitas” which is Latin for “Magnificent Humanity”. At the time I am writing, I have only skimmed over it, so my comments are only preliminary.

In the encyclical, Pope Leo explores being human in the age of technological advancements and artificial intelligence, pointing to “the grandeur of humanity,” with men and women created by God for relationship with him and each other, cooperating in God’s creative work and guided by the Holy Spirit.

The Holy Father revisits the central tenets of Catholic social teaching — the dignity of the human person, the common good, subsidiarity, solidarity and justice — as he makes the case for their use as the ethical foundation and guiding principles for the use of AI and technology.

The encyclical includes a compelling reflection on who we are called to be, “as a believer among believers, I invite everyone to contemplate, in the face of the Son of God, the grandeur of humanity that shines a light also on the era of AI… No computational system, however sophisticated, can create a heart that gives itself, or a conscience that discerns good from evil. Even when machines excel in efficiency, a human face [of the Son of God] that asks to be gazed upon remains the center of our history.” (MH, 233).

In the end, what protects us in an age of Artificial Intelligence and scientific and technological advances? Remembering they are tools we created for the good of humanity and not to reduce us to being the subject of economic, social, or political ideologies.

Blessings, Father Brad

Please pray for Garrett, all our seminarians, and for an increase in vocations. 🙏

Wall Lake native Garrett Hugeback said the excitement is “incredible” as he and his Kenrick-Glennon Seminary classmates prepare for ordination to the transitional diaconate. Hugeback and fellow diocesan seminarian Jimmy Fitzsimmons will be ordained at the Cathedral of the Epiphany in Sioux City ...

Throughout the 2025/26 formation year, Jack Jensen, a seminarian for the Diocese of Sioux City, IA, had a desire to expand his skill set in art and learn how to restore religious statuary, specifically a statue of St. Therese of Lisieux that he had received from a previous summer assignment. I think the greatest thing I took away from working alongside Jack was the fraternity spent together on Monday evenings: Matthew 18:20, “For where two or three are gathered in my name, there am I with them."
~ Joseph Bartosh - Diocese of Winona-Rochester

I asked Joseph if he’d be willing to help me fix and paint [a statue of St. Therese of Lisieux] this school year. He taught me how to paint for the first time, mixing paint to create different colors and using different brushstrokes to make the paint smooth and fit into smaller areas. Working with Joseph became my favorite part of the project. Now this statue has even more meaning as I can look back and remember the time Joseph and I spent repairing and painting this statue together.
