The first four ministers of Algiers – two French ministers and two naturalized Swiss ministers, but all four Reformed and of an evangelical bent – were true pioneers of Protestantism in Algeria. Within twenty years, they managed to assemble Protestant immigrants of different languages, nationalities, and faiths into a free community that soon became an official parish with a consistory, and later a Lutheran-Reformed Church: the mixed Protestant church of Algeria, which included a mixed parish, Reformed parishes, and Lutheran parishes. They were supported by Protestant societies in France and Geneva, by consistories and parishes in the metropolis, and by the Directory of the Church of the Augsburg Confession.
