Soltvadkert belongs to those rare Hungarian towns that have a Lutheran church in the center. This is due to the high number of German immigrants in the 18th century who built the church. Freedom of religion was, however, forbidden, and the Roman Catholic archbishop and his servants of Kalocsa have many times destroyed the church. A new Lutheran church was built in 1837, which is still in a very good shape. During the centuries, schools and other church-oriented buildings were constructed around it. The church currently has three bells in use. Inside the church there is a historical Rieger organ, which was installed in 1908. On the side of the church wall is a German sign which states: "Dies ist der Denckstein der evangelica Kirche in Vadkert" (This is the cornerstone of the Lutheran church of Vadkert). After 40 years of persecution, the Lutheran community is still active in Soltvadkert.

The Baptist mission started in 1891 in Soltvadkert. As of the year 2000, there are over two hundred followers of the church.
