instruction: List the churches serving Mayfield Park of East Bristol in a comma separated manner.
context: Mayfield Park is a residential area in East Bristol, with a large adjoining park known as the Ridgeway Rd Playing Fields.
  The area is located on the outskirts of the outer urban area of Fishponds and consists mainly of four roads: Mayfield Park, Mayfield Park North, Mayfield Park South and Mayfield Avenue. It is also near the main road of Berkeley Road and the outer urban area with the name of Speedwell, and adjacent to Chester Park. The area has a population of 1,730 (est).
  A number of churches serve the area including St John's Church of England Church, built in 1911, and St Joseph's Roman Catholic Church, built in 1925, both on Lodge Causeway. Near the park is the more modern Abingdon Road Gospel Hall, an Evangelical Church of the Noncomformist Christian Brethren built in 1937, with a large church hall backing onto the playing fields. The Morley Congregational Church originally built between Ivy Lane and Mayfield Avenue in 1889 was demolished in 1970 after it encountered structural problems, and now sites a block of modern flats.
response: The churches serving Mayfield Park of East Bristol are St John's Church of England Church, St Joseph's Roman Catholic Church, Evangelical Church of the Noncomformist Christian Brethren, and the Morley Congregational Church.
