 After a period of decline, and later of refurbishment, St. Catherine's was re-consecrated and has been the place of worship for the Anglican "CORE" church (City Outreach for Renewal and Evangelism) since then.In 1177 the parish of St. James is mentioned as part of the Augustinian abbey of St. Thomas (from which Thomas Street got its name), and the church of St. Catherine was a chapel-of-ease to the abbey.By the end of the 13th century the western suburbs had so increased in population that a separate parish was deemed necessary, which was provided for by splitting the parish of St. James and setting up an independent parish for St. Catherine's.
