Incumbents
St. Theodore's church, designed and built by John Loughborough Pearson R.A., was consecrated in 1897 as part of the Parish of Margam. In 1901 the Parish of St. Theodore, Port Talbot was formed. Since then three sections of the original parish have been redistributed to become part of the parishes of Maesteg and Margam and to form the parish of St. Agnes (now part of the Rectoral Benefice of Aberavon). In addition to the parish church of St. Theodore the parish at its formation included the Holy Cross Chapel of Ease (built 1827) and in 1915 St. Peter's Mission Church was opened in the Goytre.
