CBM preaching has taken place since the early 1980s with campaigns and a regular missionary presence in Dublin. A weekly Bible reading group is held in Dublin, where a rented flat is used as a base. Seminars have been held in Dublin and Cork. There are members in isolation in Cork, Galway, Limerick, Nenagh and Clonmel. There are about 26 members in total.
