St. Mary's Church, Geraldine, is a fine brick building, erected in 1881, to replace an old wooden church built in 1864. There is seating accommodation for 280 persons, and the average attendance is 100. There is a surpliced choir, which is accompanied by a large American organ. The church has a fine oak lectern, erected to the memory of the late Rev. J. Preston, who was vicar of the parish for twenty-eight years. Services are held twice every Sunday at St. Mary's; also at St. Thomas', Woodbury, and St. Stephen's, Peel Forest, every Sunday, and at Mount Peel and Pleasant Valley, once a month.

The Rev. Staples Hamilton, B.A., vicar of St. Mary's, Geraldine, was born in Yorkshire, England, in 1859, educated at Christ's Hospital, London, and came to New Zealand by the ship “Langston,” in 1875. He finished his course of studies at Canterbury College, where he gained his degree, and was ordained by Bishop Harper. Mr. Hamilton was first appointed curate at Sumner, near Christchurch. He subsequently spent eleven years at Leeston, and was appointed to All Saints', Hokitika, in 1894. From Hokitika he removed to Geraldine.
