The parish of Ashmansworth is in the Diocese of Winchester. Services are held regularly as well as Baptisms, Weddings, and Funerals. The church plays an important part of this village community and its clergy give vital pastoral care to the parishioners.
The building itself is Grade 1 listed and is of historic importance. The Nave dates back to the 12th Century whilst parts of the building are even older. The two porch windows were designed by Sir Lawrence Whistler and dedicated to Joy, wife of the celebrated composer Gerald Finzi, and to English composers. Personal donations are the primary source of income to run and maintain the church.
