Published in 1581, the Harmonia confessionum fidei (Harmony of Confessions of Faith) was an early attempt at Protestant comparative dogmatics or symbolics.
It grew out of a desire for one common Creed, which was modified into the idea of a selected harmony.
Jean-François Salvart, minister of the Church of Castres, is now recognized as the chief editor of the work with some assistance from Theodore Beza, Lambert Daneau, Antoine de la Roche Chandieu, and Simon Goulart.
It was intended as a defense of Protestant, and particularly Reformed, doctrine against the attacks of Roman Catholics and Lutherans.
It does not give the confessions in full, but extracts from them on the chief articles of faith, which are classified under nineteen sections.
