Calvary Church is the result of the actions of a group of individuals from Mannheim Mennonite Church.  They had a burden to do outreach work, and they began with a Sunday School work in the community of Reidsville, just north of the village of Ayr.  This group met in various locations, until the group purchased a property in Ayr in 1960.  They soon erected a church building, and in 1970, they built a parsonage beside it.   In 1978, needing more room, a portable was placed behind the church building, but it wasn’t long before there was a building project, and the portable became part of the original building.  In May of 1990, by selling the old parsonage, holding fund-raisers, collecting private donations, selling the church building, to Kipp’s Funeral Home of Paris, enough money was raised to construct the present facility.  Many church members, and many volunteers gave of time and effort in order to help reduce costs.  The $200,000 mortgage was completely paid by 2001.

Calvary Church started as a mission, and that heart for mission work continues.  Two intergenerational groups were dispatched to Buffalo, NY to clean up an old television studio to be converted into a mission center, a group of youth went to Montreal to work in a soup kitchen, a Mission went to Haiti to help rebuild a hospital.  In 2005 a Skatepark was opened in the rear of the property as an outreach to the youth of Ayr.  In 2007, a team went to Mexico City to work in an orphanage. Support was sent Derek & Vicki Martin and their work at Labrador Christian Youth Camp in 2007-8.   In 2008, two men were commissioned to be part of SWAP – Sharing With Appalachian Peoples and worked on wheelchair ramps, roof repairs, etc for the community of Eolia, Kentucky.  Volunteering at local mission agency is vigorously encouraged.
