Bahá'í literature directs that a House of Worship should be built in each city and town, and emphasizes that its doors must be open to all regardless of religion, or any other distinction. The Bahá'í laws emphasize that the spirit of the House of Worship must be a gathering place where people of all religions may worship God without denominational restrictions. The Bahá'í laws also stipulate that only the holy scriptures of the Bahá'í Faith and other religions can be read or chanted inside in any language; while readings and prayers may be set to music by choirs, no musical instruments may be played inside. Furthermore, no sermons may be delivered, and no ritualistic ceremonies practiced.
