A U.S.-based biotech company has announced the launch of Nucleus Embryo, a company that screens human embryos for desired genetic profiles, a practice the Catholic Church teaches violates human dignity and contributes to a eugenic mentality. 

People undergoing in vitro fertilization (IVF) will be able to screen up to 20 embryos for over 900 conditions and traits, including health risks, intelligence, and physical characteristics like height and eye color, in order to “optimize” their embryos, according to Kian Sadeghi, founder of Nucleus Genomics, parent company of Nucleus Embryo.

“I see a world where sequencing, analyzing, and editing DNA merge seamlessly to create a truly preventative health care system,” the 25-year-old Sadeghi said on the company’s website, adding: “Every parent wants to give their children more than they had. For the first time in human history, Nucleus adds a new tool to that commitment.”

Embryos that meet parental desires will be eligible for implanting, and undesirable ones will be discarded.

While the Catholic Church teaches that IVF is morally illicit because it completely separates procreation from the marital act and violates the dignity of the child, the Church also condemns preimplantation diagnosis as “shameful and utterly reprehensible,” an “expression of a eugenic mentality” that leads to the destruction of innocent human life.

Published by the Dicastery for the Doctrine of the Faith, the 2008 document Dignitatis Personae affirms that the human embryo cannot be treated as “mere laboratory material” because this violates its dignity, which “belongs equally to every single human being, irrespective of his parents’ desires, his social condition, educational formation, or level of physical development.”

The document explicitly condemns preimplantation diagnosis and resulting genetic enhancements because they can result in the killing of human embryos “affected by various types of anomalies,” and they “presume to measure the value of a human life only within the parameters of ‘normality’ and physical well-being, thus opening the way to legitimizing infanticide and euthanasia.”

Such procedures could also marginalize individuals, widen societal divides, and “harm peaceful coexistence among individuals,” the dicastery stated.  

The document questioned who would establish which gene edits were worthwhile and which were not, and what limits, if any, should be placed on genetic enhancements “since it would be materially impossible to fulfill the wishes of every single person.”

In the end, the common good will be harmed by “favoring the will of some over the freedom of others.”

National Catholic Bioethics Center senior ethicist Father Tad Pacholczyk told CNA that “couples will now be tempted to impose quality control and eugenics onto their vulnerable and voiceless children.”

Nucleus Embryo’s website emphasizes genetic manipulation of embryos before implantation and states: “The best time to prevent disease is pre-pregnancy. Knowing what you could pass on to your kids lets you plan with clarity and avoid future surprises.”

This is a “‘command and control’ mentality over procreation,” Pacholczyk said, which allows people to treat their “own offspring like raw material … It’s tragic when our children become a mere abstraction, pawns to be played in the end game of seeking what we want.”

“Society’s demand for physical perfection places untold pressure on couples today to ‘conform to the norm’ by aborting or otherwise eliminating any less-than-perfect children,” he continued.

“Human embryos, among the most vulnerable of God’s creatures, have been entrusted to us to be received unconditionally and lovingly by all parents, without demanding that they run any gauntlet of prenatal screening. Every child, exactly as he or she arrives into our families, is precious, good, and beautiful.”

Pacholczyk said not every use of prenatal diagnostic information is morally unacceptable, however. 

Diagnostic information that “assists in the treatment of an in-utero patient represents a morally praiseworthy use of this powerful technology.”

For example, a life-threatening disease known as Krabbe’s leukodystrophy can be treated through a bone marrow transplant immediately following a child’s birth. If the disease is diagnosed prenatally, the parents can look for matching bone marrow before the child is born. Certain other diseases, such as spina bifida, can also be surgically treated prenatally.

Cardinal Ambongo appeals to Trump: ‘Africa is important to the U.S.’

Washington, D.C. Newsroom, Jun 10, 2025 / 15:19 pm (CNA).

Cardinal Fridolin Ambongo asked U.S. President Donald Trump this weekend to reinstate foreign aid to Africa. 

“Targeted humanitarian aid for Africa is urgently needed, morally good, and of great strategic value to the U.S,” Ambongo, the archbishop of Kinshasa in the Democratic Republic of Congo, wrote in an op-ed published in the Wall Street Journal on Sunday afternoon. 

“​​President Trump has made clear that he will put the needs of his country and its citizens first before attending to the needs of the world. No leader of a nation as great as the U.S. could do otherwise,” the cardinal stated. “It would be a mistake, however, for Mr. Trump to forget about Africa.”

Ambongo highlighted Africa’s rich natural resources and “bright entrepreneurial and eager young people” as important assets to the U.S., emphasizing the utility of a relationship between Africa and the United States. 

American generosity toward Africa through USAID has “transformed millions of lives for the better” in the region, Ambongo said, pointing out that American aid has helped enhance African society and avert further political and economic crises threatening the continent’s development. In the process, he noted, American economic influence in the region has been strengthened.

With the freezing of critical aid to African countries, the cardinal described Africa as “a magnet for conflicts and fights over the natural resources so important to modern technology.” 

He also noted pervasive famine and poverty plaguing many parts of the region. 

While Ambongo acknowledged the need for the U.S. to be concerned about the use of its limited resources, he noted that international adversaries will replace the U.S. if it completely withdraws all aid to Africa.

“International politics won’t tolerate a vacuum,” he predicted. “Should the U.S. abandon Africa, its place will be taken by its adversaries: China, Russia, Iran, North Korea.”

The cardinal stressed that “it isn’t too late to turn the tide” and reach a mutually beneficial solution that does not exploit U.S. resources for ideological causes that run counter to African values by providing aid that supports abortion services and contraception in the region. 

“It’s unhelpful to tie aid to ideology — to abortion or ‘population control’ — that defies the values of many African cultures,” he said. “I believe that respect for African culture can coexist with humanitarian aid. Cultural colonization needn’t be the price exacted for a moral, strategic, and humanitarian partnership.” 

Ambongo’s remarks on the politicization of humanitarian aid come after the U.S. State Department announced its plans to destroy a reserve of artificial contraceptives that was previously set aside for distribution in developing countries through foreign aid programs. 

Pleading on behalf of bishops, priests, and laypeople in Africa, Ambongo urged Trump and his administration “to reconsider aid to his friends in Africa, who have been and will continue to be important partners of the U.S.” 

“We are eager to work closely with Washington to ensure that all such aid is used well, free of the fraud and mismanagement that has occurred in the past,” he concluded. “There is too much at stake — for Africans, for Americans, and for the world.”

Pope Leo XIV: The Church ‘will always defend the sacred right to believe in God’

Vatican City, Jun 10, 2025 / 14:11 pm (CNA).

Pope Leo XIV received papal representatives at the Vatican on Tuesday, reminding them that the Church “will always defend the sacrosanct right to believe in God” and that this life “is not at the mercy of the powers of this world.”

In the June 10 speech delivered in the Clementine Hall of the Vatican Apostolic Palace, he thanked the papal nuncios and international organizations around the world for their work.

The pontiff noted that “there is no country in the world” with a diplomatic corps as universal and united as that of the Holy See: “We are united in Christ and we are united in the Church.”

“I say this thinking certainly of the dedication and organization, but, even more so, of the motivations that guide you, the pastoral style that should characterize you, the spirit of faith that inspires us,” he added.

He particularly thanked them for being able to rely on the documentation, reflections, and summaries prepared by the diplomats when faced with a situation that concerns the Church in a particular country. “This is for me a cause for great appreciation and gratitude,” he reiterated.

‘Always be the eyes of Peter!’

Pope Leo XIV then shared with those present the account from the Acts of the Apostles (3:1-10) of the healing of the paralytic, a scene that, in his opinion, “describes the ministry of Peter well.”

For the pontiff, the man who begs for alms at the Beautiful Gate of the Temple represents “the image of a humanity that has lost hope and is resigned.”

“Even today, the Church often encounters men and women who no longer have any joy, whom society has sidelined, or whom life has in a certain sense forced into begging for their existence,” he lamented.

After looking into his eyes, the pope recounted, Peter said to the paralytic: “I have neither silver nor gold, but what I do have I give you in the name of Jesus Christ the Nazorean, [rise and] walk.”

After quoting this passage, Pope Leo noted that “to look into one’s eyes means to build a relationship. The ministry of Peter is to create relationships, bridges: and a representative of the pope, first and foremost, serves this invitation to look into the eyes.”

“Always be the eyes of Peter! Be men capable of building relationships where it is hardest to do,” the pope exhorted them, asking them to do so with humility and realism.

The Holy Father also placed his trust in the diplomatic corps of the Holy See so that “everyone may know that the Church is always ready for everything out of love, that she is always on the side of the last, the poor, and that she will always defend the sacrosanct right to believe in God, to believe that this life is not at the mercy of the powers of this world but rather is traversed by a mysterious meaning.”

He also encouraged them to “always have a blessing gaze, because the ministry of Peter is to bless, that is, always to know how to see the good, even that which is hidden.”

“Feel that you are missionaries, sent by the pope to be tools of communion, unity, serving the dignity of the human person, promoting sincere and constructive relations everywhere with the authorities with whom you are required to cooperate,” he urged.

In conclusion, he reiterated that their work “always be enlightened by the sound decision for holiness.”

After the speech, the papal representatives received a ring bearing the inscription “sub umbra Petri” (“under the shadow of Peter,” cf. Acts 5:15) from the pope as a sign of communion.

Chartres pilgrimage draws 19,000 in show of faith and tradition

CNA Staff, Jun 10, 2025 / 13:33 pm (CNA).

The 43rd annual Paris-Chartres pilgrimage concluded on Monday with a solemn high Mass at Chartres Cathedral, marking the end of a record-breaking three-day journey that drew 19,000 participants — the largest attendance in the event’s four-decade history. 

The three-day trek from Paris to Chartres represents a demanding challenge — one both physical and spiritual — that continues to attract growing numbers of young Catholics seeking deeper spiritual experiences. 

Organized by Notre-Dame de Chrétienté, the pilgrimage began on Saturday, June 7, at Saint-Sulpice Church in Paris and concluded at the Gothic cathedral, which houses the sacred relic of the Virgin Mary’s veil.  

Bishop Philippe Christory of Chartres delivered the homily at the closing Mass, celebrated by Abbé Jean de Massia, FSSP, the pilgrimage’s general chaplain. 

Christory reportedly told the pilgrims before Mass: “We know that Pope Leo prays for every pilgrim to live a personal encounter with Christ.”

Registration for this year’s pilgrimage closed within five days of opening, necessitating a waiting list of 2,000 additional participants. The average age of pilgrims was 20 years old, reflecting a broader trend among young Catholics who are gravitating toward traditional liturgy. 

“The enthusiasm sparked by all the pilgrimage opportunities in France — especially those for young people — is a joy for the Church and a sign of its vitality,” the French Bishops’ Conference stated. 

The event’s growth in recent years has been remarkable, increasing from 16,000 participants in 2023 to 18,000 in 2024 and now to 19,000 in 2025.  

Philippe Darantière, president of Notre-Dame de Chrétienté, indicated that organizers are already planning structural changes for 2026 to accommodate even greater numbers. 

The pilgrimage maintained its traditional character, with more than 300 Latin Masses celebrated throughout the three days. Participants walked approximately 60 miles (100 kilometers) through the French countryside, praying the rosary and camping overnight at designated sites. More than 1,000 volunteers and 120 executives from Notre-Dame de Chrétienté supported the pilgrims during their journey.

The closing ceremony coincided with Chartres Cathedral’s millennium jubilee celebration, allowing pilgrims to pass through the Holy Doors and venerate the relic of the Virgin Mary’s veil.  

The Notre-Dame de Chrétienté association also consecrated itself to the Sacred Heart of Jesus, marking the 350th anniversary of Christ’s apparitions to St. Margaret Mary Alacoque.

Blessed Edward Poppe

Blessed Edward Poppe

Feast date: Jun 10

Blessed Edward Poppe is a contemporary saint. He died at the young age of 33.

He was an energetic child and an excellent student. His mischievousness saw him often knock things over even putting himself at risk of being harmed. He was also quite stubborn and never left his sisters alone though his sisters would often get back at him and would muss up his hair when he was caught combing in front of the mirror. He was also a big eater and liked to devour treats from his father's store. But in 1902 he received his First Communion and Confirmation and this made him more serious which meant jokes and teasing became rarer.

In spring 1904 his father introduced him to his business plans and had hoped to see his son begin a baking apprenticeship though Poppe remained silent at first though his resolution to become a priest led him to tell his father as much. Not long after a priest friend to his parents gave a favorable opinion of Poppe's vocation to which his father told his mother: "Let's not be selfish. God has not given us our children for ourselves".

He was one of 11 children born to a modest, pious family in Belgium. One of his brothers had become a priest, and five of his sisters became nuns. He felt a call to the priesthood at a young age, but he only entered the seminary on his mother’s insistence. His father had died when he was 16 years old and Edward thought he should take on the family business.

He was drafted to the military in 1910 and served as a battlefield nurse during World War I. His prayers to St. Joseph during that time led to the miraculous freeing of several prisoners of war.

He was finally ordained in 1916 at the age of 25 and served as associate pastor, focusing his ministry to the poor, children and the dying. He also taught catechism and founded Eucharistic associations.

Always a man with a weak constitution, he was transferred to rural Belgium. In 1919, he suffered a heart attack. During his convalescence, he spent most of his time studying, praying and producing thousands of writings against Marxism and secularization.

He also developed a devotion to St. Therese of Lisieux and adopted her spirituality. He had another heart attack in January 1924, and died of a stroke only six months later. He was beatified by Pope John Paul II in 1999.
