Quick answer: Sts Sixtus II & Companions and St Cajetan are commemorated together on 7th August each year. Sixtus II was a third-century pope martyred during the Valerian persecution in 258 AD, while Cajetan was a 16th-century Italian priest who co-founded the Theatine order and devoted his life to caring for the sick and poor.
Every year on 7th August, the Catholic Church marks one of its lesser-known double feasts — honouring both Pope Sixtus II and St Cajetan on the same day. For many Catholics in the UK, this date passes quietly. No bank holiday, no widespread celebration, no greeting cards in the shops. Yet these two saints represent something enduring: the courage to lead and serve, even at great personal cost.
This guide explores who Sixtus II and Cajetan were, why they are remembered together, and what their lives mean for Catholics in Britain today — particularly as 2026 brings renewed interest in the liturgical calendar and the broader tradition of saints’ feast days.
Who Was Pope Sixtus II, and Why Was He Martyred?
Sixtus II served as Bishop of Rome from 257 AD until his death in 258 AD — one of the shortest and most turbulent pontificates in early Church history. He came to power at a time of relative calm following the persecutions of Emperor Decius, and his early tenure was marked by attempts to resolve theological disputes, including a significant disagreement with St Cyprian of Carthage over the validity of baptisms performed by heretics.
That calm did not last. In 257 AD, Emperor Valerian issued a series of edicts targeting Christian clergy and communities. Bishops, priests, and deacons were ordered to perform Roman religious rites. Those who refused faced exile, imprisonment, or death.
Sixtus II refused.
On 6th August 258 AD — the same day as the feast of the Transfiguration — he was arrested while presiding over a liturgy in the cemetery of Praetextatus in Rome. He was executed the following day, along with four of his deacons. Four more companions, including the beloved St Lawrence, were killed in the days that followed.
The Church commemorates Sixtus II not on the day of his arrest, but on 7th August — the day of his death and the day he formally entered the ranks of the martyrs.
Who Were the Companions of Sixtus II?
The companions martyred alongside Sixtus II include deacons Felicissimus and Agapitus, who died on the same day. St Lawrence, arguably the most famous of the group, was martyred three days later on 10th August — a date that carries its own feast day in the liturgical calendar.
Together, these figures are remembered as witnesses to the early Church’s refusal to compromise its faith under imperial pressure. Their collective feast is a reminder that martyrdom was rarely solitary; it was communal.
Who Was St Cajetan, and What Did He Build?
St Cajetan (also written as Gaetano) was born in 1480 in Vicenza, in what is now northern Italy. Educated in law and theology, he initially pursued a career in papal administration before feeling called to a more radical form of Christian life — one centred on poverty, service, and reform.
In 1524, Cajetan co-founded the Theatine order alongside Gian Pietro Carafa, who would later become Pope Paul IV. The Theatines were a congregation of clergymen who lived in apostolic poverty, renounced all fixed income, and dedicated themselves entirely to the care of the sick and the poor. At a time when corruption within the Church was a source of widespread scandal, the Theatines represented a grassroots effort at renewal from within.
Cajetan was particularly drawn to those whom society marginalised — the destitute, the incurably ill, and those dying without access to sacraments. He established hospitals and houses of care across Italy and is credited with inspiring later reforms that shaped the Counter-Reformation.
He died on 7th August 1547, in Naples. He was canonised by Pope Clement X in 1671.
Why Are Sixtus II and Cajetan Celebrated on the Same Day?
The pairing is historical rather than theological. Both saints died on 7th August — Sixtus in 258 AD, Cajetan in 1547 AD — separated by nearly thirteen centuries. When the Church assigns feast days, martyrs and confessors are typically commemorated on the anniversary of their death, which is understood as their true birth into eternal life.
The shared date means that 7th August has long held a double meaning in the Roman Rite: a day of martyrdom and a day of merciful service.
What Does the 2026 Observance Look Like in the UK?
In 2026, 7th August falls on a Friday. It is an optional memorial in the Roman Catholic Church, meaning it is not a holy day of obligation but is included in the liturgical calendar and may be observed in parish Masses and personal devotion.
For Catholics in the United Kingdom, optional memorials are often quietly observed — included in the prayers of the faithful, referenced in a priest’s homily, or marked through personal reflection. Parishes with particular devotions to early martyrs or to the charism of service to the poor may choose to celebrate the memorial more formally.
The feast holds particular resonance for those involved in Catholic healthcare, social work, and pastoral care — fields that align closely with Cajetan’s founding vision for the Theatines.
What Can British Catholics Learn From These Two Saints?
Sixtus II and Cajetan are separated by more than a thousand years, yet they share something essential: both made costly choices in service of others. Sixtus chose death over apostasy. Cajetan chose poverty over comfort, and built institutions to serve those no one else would.
For Catholics in Britain, their stories offer a grounding that cuts through the noise of contemporary life. They are not saints defined by miracles or dramatic visions, but by the quieter — and perhaps harder — work of fidelity.
Cajetan’s model is especially relevant to the UK context. The National Health Service, the welfare state, and the broader tradition of charitable care that shapes British civil society all draw, at least partly, from a Christian anthropology that insists on the dignity of every person. Cajetan embodied that principle before it had a name.
How Can You Mark the Feast of Sts Sixtus II and Cajetan in 2026?
There is no single prescribed way to observe an optional memorial, but a few approaches are common among practising Catholics:
- Attend Mass on 7th August, where the priest may include reference to the feast.
- Read about their lives using resources from the Catholic Truth Society or the Vatican’s official martyrology.
- Volunteer or donate to a Catholic charity working with the sick or poor — a direct expression of Cajetan’s charism.
- Pray the Liturgy of the Hours for 7th August, which includes antiphons and readings specific to the memorial.
A Final Thought on Forgotten Feast Days
The liturgical calendar is dense with saints whose stories deserve more attention than they typically receive. Sixtus II and Cajetan are not household names — not even within practising Catholic communities in the UK. But their lives carry weight precisely because they were ordinary people who made extraordinary commitments.
Sixtus led a Church through persecution and died for it. Cajetan built something new because the existing structures weren’t reaching people who needed help most. Both responses — steadfast witness and practical reform — remain relevant to Catholic life today.
As 7th August 2026 approaches, it is worth taking a moment to learn their names, understand their stories, and consider what their examples might mean for the way we live and serve.

What is the Theatine order, and does it still exist?
Yes. The Theatines (formally the Congregation of Clerks Regular) were co-founded by St Cajetan in 1524 and continue to operate today, primarily in pastoral and educational ministry across Europe, the Americas, and parts of Africa and Asia.
Why are two unrelated saints celebrated on the same day?
Both Sixtus II and Cajetan died on 7th August — in 258 AD and 1547 AD respectively. The Church commemorates saints on the anniversary of their death, so the shared date is coincidental but historically significant.
How is St Cajetan relevant to Catholic social teaching?
Cajetan’s commitment to the care of the sick and poor prefigures many of the principles articulated in modern Catholic social teaching, particularly the preferential option for the poor and the inherent dignity of every human person. His work is considered an early example of institutional charitable care within the Church.
