Amid record-breaking summer heat across Europe, the Vatican has introduced a new liturgy that places ecological concern at the center of worship.

According to The Salt Lake Tribune, the new Mass, titled "Pro Custodia Creationis" — "For the Care of Creation" — underscores the Catholic Church’s growing focus on environmental issues and aligns with the 10th anniversary of Pope Francis’ encyclical "Laudato Si’."

Announced Thursday at a Vatican news conference, the Mass introduces Scripture, prayers and hymns centered on safeguarding creation as a moral and spiritual imperative. It was commissioned by Pope Francis and affirms Pope Leo XIV’s continuation of environmental concern as a core Catholic theme.

New Liturgy Reinforces a Decade of Teachings

Cardinal Michael Czerny, head of the Dicastery for Integral Human Development, presented details about the new Mass, which he said "can be used to ask God for the ability to care for creation." Czerny explained that protecting Earth is no longer merely a social issue but a moral requirement of faith.

The new Mass is an official addition to the Church’s 17 approved liturgies that respond to contemporary social needs, such as for peace, rain, or for those displaced by conflict. Created in collaboration with the Dicastery for Divine Worship, the service reflects 10 years of theological focus on the environment since the release of “Laudato Si’.”

The liturgy echoes teachings from previous popes, including St. John Paul II, whose 1990 World Day of Peace message emphasized respect between humanity and the natural world. That message was among the inspirations for creating this latest worship rite.

Liturgy Highlights Human Responsibility to Nature

The opening of "Pro Custodia Creationis" focuses on revering Earth as a testament to divine glory. Monsignor Vittorio Francesco Viola explained that the start of the Mass draws from biblical imagery to frame creation as a reflection of God’s beauty and purpose.

Scripture readings include well-known passages from the Gospel of Matthew, such as Jesus’ teaching about divine care for the lilies of the field and the birds of the air. Further readings recount Jesus calming the storm, illustrating the interconnectedness of God, nature, and humanity.

Viola noted that these selections aim to move beyond misinterpretations of the Book of Genesis that have historically justified dominance over nature, instead promoting stewardship rooted in humility and gratitude.

Private Celebration to Mark the Message

Pope Leo XIV, who has reinforced environmental concern as a pastoral goal, plans to celebrate the liturgy privately at the eco-oriented Borgo Laudato Si’ village. Located within the papal summer residence of Castel Gandolfo, the venue was established by Pope Francis as a model for sustainability in Church life.

The Eucharistic celebration concludes with a prayer calling attention to broken relationships — between humanity and God, each other, and Earth. Viola explained that the final prayer offers a moment of reflection on sin’s damaging effect on ecological and human harmony.

Cardinal Czerny emphasized that the Mass not only serves as a form of worship but also fosters deepened commitment to care for the planet. He said embracing this responsibility in prayer helps translate spiritual belief into real-world action.

Faith and Climate Justice Now Intertwined

“This Mass is a reason for joy,” said Czerny. He described the liturgy as a new expression of faith in a time when ecological degradation disproportionately affects the already vulnerable.

“Care for creation becomes an expression of our faith and humanity,” Czerny said, adding that believers are called to protect the Earth through daily choices, public policies, and worship practices alike.

The Vatican’s move comes at a time when environmental issues are increasingly shaping both theology and social engagement in religious communities across the globe. The Church hopes this new focus within the liturgy will help galvanize these efforts.
