Belonging to the Lutheran Church of Sweden, it is part of Kafjärden Parish in the Diocese of Strängnäs.

Jäder Church is a significant work of Swedish renaissance architecture, and is sometimes locally jokingly referred to as Rekarne domkyrka, "Rekarne Cathedral", owing to its unusually large size for a village church and extensive renaissance decorations.

The church is situated on a hill surrounded by fields and built in stone and brick.

The exterior is mainly characterised by the brick walls and mid-17th century ornamental sandstone decorations on the gables.

The late Gothic winged altarpiece in Brabant style was originally commissioned for Storkyrkan in Stockholm and is one of the foremost examples of this altarpiece style in Sweden, built 1514 in Jan Borman's workshop in Brussels and painted by Jan van Coninxlo the Younger.
