An Ancient Worship Movement invites readers into the rich, historic worship of the early Church rediscovered through the Anglican tradition. This book calls believers into a deeper, Spirit-filled encounter with Christ through timeless practices.

The re-evangelism of post Christian western culture is one of the mandates of St. Thomas Church. Liturgical Churches were the formation of Christian culture in the west with historical creeds of the Church. Many are looking for this substance and foundation of what early Christians believed and died for in the pre-Constantine era. This dependence on early Church disciplines and practices that have stood the test of time which have been carried on by Apostles and bishops gives us confidence that we are perpetuating the ancient faith (Jude 1:3).

COMMON QUESTIONS

St. Thomas Church affirms the core Biblical doctrines upheld by the global Christian Church for centuries. Our beliefs align with historic Protestant theology, and we incorporate the Apostles’ Creed and Nicene Creed into our worship services, reflecting our commitment to timeless Christian truth.

When you visit St. Thomas Church, anticipate a reverent gathering focused on worshiping the Triune God.

Here’s what to expect:

  • Christ-Centered Worship: The service centers on Jesus Christ, with an altar and cross as focal points, directing all attention to Him.
  • Quiet Reverence: Before the service, you’ll find a hushed atmosphere of prayer, not casual conversation, fostering a sacred space.
  • Liturgical Worship: You’ll receive a liturgy book or printed guide to follow along with ancient prayers and creeds, connecting you to nearly 2,000 years of Christian tradition.



Prepare for a deeply spiritual experience rooted in Scripture and historic worship practices.

St. Thomas Church stands out from many modern churches through its distinctive practices, blending ancient Christian traditions with a vibrant mission.

Key distinctives include:

  • Facing the Altar: Worship is directed toward God, with the altar as the focal point, emphasizing divine reverence over human performance.
  • Head Coverings for Women: Sisters wear veils during services, symbolizing the presence of holy angels in worship.
  • House Churches: Many of our congregations meet in homes, creating intimate, community-driven settings for liturgical worship.
  • Role of Women: In keeping with ancient practices, women do not lead services, honoring distinct roles in gathered worship.
  • Ancient and Modern Worship: We combine timeless liturgical elements with select modern expressions for a rich, meaningful experience.
  • Multiplying Churches: Like the early church in Acts, we aim to rapidly plant and grow liturgical communities worldwide.
    These practices reflect our commitment to Biblical fidelity, historic tradition, and active Gospel mission.

St. Thomas Church is a church planting movement, not a single congregation. We are a network of parishes and individuals united in worship, prayer, and mission, with a focus on starting liturgical churches, often in homes, across North America and beyond. Like the early church in the Book of Acts, we emphasize simple devotion to Jesus Christ, equipping and supporting new gatherings to grow and multiply in homes and other settings.
