The church building was originally built and housed a
Lutheran congregation under the name of the Peace Lutheran Church. The building was put up for auction as Peace Lutheran consolidated its parish with a number of other Lutheran congregations on Chicago's
Northwest Side.
St. John of Rila is important for
Bulgarians in Chicago because national churches in America, in addition to being places of worship, are social center devoted to maintaining the language, culture and tradition of the Bulgarian
diaspora through
Sunday schools and social gatherings. In October 2003,
Princess Marie Louise of Bulgaria toured the church. ==Architecture==
