About the CACI

Welcome to the Celtic Anglican Communion International

The Celtic Anglican Communion International is a communion of independent congregations, ministries, and clergy who stand within the living tradition of Celtic Christianity. We are an independent Catholic Christian jurisdiction, grounded in the historic faith of the Church and open to the ongoing movement of the Holy Spirit today.

We offer an unconditional welcome to all. Our mission is to create sacred spaces where every person may experience connection with God, with one another, and with the whole of creation. We celebrate and honor God’s boundless love revealed in Jesus Christ and affirm that no one is excluded from that love.

We invite you to explore the rich spiritual heritage of Celtic Christianity and to consider joining us on this shared journey of faith, prayer, and service.

Our History

The Antiquity of the Celtic Church

Our history reaches back to the earliest expressions of Christianity that took root in the Celtic lands within the first centuries following the Crucifixion. The Christian Church in Britain traces its origins to the early Church, with historical and patristic sources attesting that Christianity was present in Roman Britain by at least the second century—well before the mission of St. Augustine of Canterbury in 597 CE.

Early British Christians remained in communion with the wider catholic Church while developing distinctive spiritual expressions shaped by monastic life, devotion to Holy Scripture, ascetic discipline, missionary zeal, and a profound reverence for God’s creation.

Writers such as Tertullian (c. 200 CE) record that even regions of Britain “inaccessible to the Romans” had received the Gospel. British bishops participated in the Councils of Arles (314 CE), Sardica (343 CE), and Ariminum (359 CE), demonstrating that the British Church possessed an established episcopate and apostolic order from an early date.

Following the withdrawal of Roman authority, Christianity did not disappear from Britain. Instead, it continued to flourish throughout the Celtic lands of Britain, Ireland, and Scotland, giving rise to great missionary saints such as Patrick, Ninian, Columba, Aidan, Hilda, and many others. The British and Celtic Churches preserved apostolic faith and sacramental life while emphasizing monastic leadership, pastoral care, and evangelistic mission.

This ancient Church stands as a living witness to the continuity of Christian faith in the British Isles from the early Church through the Celtic era and beyond.

Our bishops trace their apostolic succession through historic ecclesial lines that include connections to Glastonbury Abbey, through three historically attested abbots and at least two abbots preserved in ancient tradition. According to long-held Christian legend, Joseph of Arimathea is believed to have journeyed to Glastonbury and established what is regarded as the first legally sanctioned Christian church in the land, with the consent of a local king. While this account belongs to sacred tradition rather than documented history, it reflects the deep antiquity and spiritual significance long associated with Glastonbury as a center of early British Christianity.

 

What Is a Celtic Anglican Benedictine?

A Celtic Anglican Benedictine is a Christian—lay or ordained—who follows Jesus Christ within the Anglican tradition, lives according to the Rule of St. Benedict, and draws spiritual inspiration from the ancient Celtic Christian Church of the British Isles.

Celtic

The Celtic aspect reflects the spirituality of early Christianity in Britain, Ireland, and Scotland. It emphasizes:

  • A deep awareness of God’s presence in everyday life

  • Reverence for creation as God’s handiwork

  • Missionary and monastic roots

  • Prayer that flows from Scripture and daily life

  • Hospitality, community, and pilgrimage

Celtic Christianity is experiential, incarnational, and grounded in the rhythms of prayer and work.

Anglican

The Anglican identity situates this spirituality within the Anglican tradition, marked by:

  • The authority of Holy Scripture, interpreted through tradition and reason

  • The historic episcopate and sacramental life

  • The Book of Common Prayer as a foundation for worship

  • A commitment to unity, pastoral care, and the via media

Anglicanism provides theological balance and ecclesial structure.

Benedictine

The Benedictine element reflects a life shaped by the Rule of St. Benedict, centered on:

  • Ora et Labora (Prayer and Work)

  • Stability, obedience, and conversion of life

  • Community life rooted in humility and mutual service

  • Regular rhythms of prayer, especially the Daily Office

  • Hospitality as a sacred duty

The Rule offers a practical framework for living the Gospel faithfully in community and ministry.

This vocation is especially suited to pastoral, missionary, chaplaincy, and contemplative ministries—where prayer, presence, and service are held together.
