They are a full member of the Anglican Communion as a Church of Ireland place of worship. Their goal is to be at the centre of the community, increasing commitment, outreach, worship, and demonstrating Christian love, as well as offering a warm welcome to everyone, regardless of colour, creed, or class. Their beliefs are encapsulated in the Apostles’ Creed and the Nicene Creed.

Their church was intended to be a part of the new town of Enniskillen, which was built on King James the First of England’s instructions in the years following 1611. The original church structure was most likely built around 1627. One of the founders, Richard Pokrich, had a son named William who, unfortunately for Richard, was the first person to be buried in the cemetery in 1628. William’s tombstone has been incorporated onto the cathedral’s wall for everyone to see.

Although little of the ancient church survives, a portion of its tower was integrated into the current one and can be seen above the main entry door, where there is a tiny, antique three-light lattice window and a carved stone dated 1637, as well as the Agnus Dei (Lamb of God).
