AN 87-year history will come to an end when Minyip Uniting Church closes on Sunday.
Committee secretary Helen Barry said 120 people including past ministers and members of the congregation would attend a 2.30pm service.
The service will be followed with afternoon tea at Minyip Senior Citizens Hall.
Mrs Barry said a declining population had led to the decision to close the church.
"Unfortunately church numbers had declined to the point where the committee decided to sell the church," she said.
"It's a sign of the times, despite the church's great history.
"Both the church and the Sunday school hall, which is currently running as an op shop, will eventually be sold.
"The op shop will continue to run until that happens."
Mrs Barry said any former members were welcome to attend the service and afternoon tea.
"We will be like sardines in the church - it only seats 90, but we will squeeze in some extra chairs and would like to see anyone who has a history with the church, whether they were married or baptised there," she said.
St Andrew's Presbyterian Church - a stone building featuring stained-glass windows depicting Bible stories - was built in 1925.
Presbyterian Church of Australia moderator general Rev Crookston opened the church on November 29, 1926.
The church merged with the Methodist Church in Minyip in 1972 under the guidance of Rev W. Adrain.
Rev Eil Kingma was minister from 1976 when the church became part of the Uniting Church of Australia.
Services alternated monthly between the Presbyterian and Methodist church buildings until 1983, with the Methodist church building sold in 1984.
St Andrew's Presbyterian Church then became the Minyip Uniting Church.
Florence Penny was the organist for a remarkable 76 years, commencing in 1922 when she was a teenager and retiring in 1998 when she was in her 90s.
Mrs Barry said in its time the church had an active youth group and Presbyterian Women's Missionary Union group which then became the Uniting Church Adult Fellowship group.
Both groups eventually closed due to lack of numbers.
