Swiss, and especially British preachers travelled all over France spreading the Revival Movement. Ami Bost and Charles Cook were the best-known, and introduced Anglo-Saxon customs, such as small group meetings rather than large assemblies, hymn singing with romantic words and music, whereas the reformed would traditionally sing psalms only.
In Paris the Revival Movement influenced the upper middle-class and penetrated aristocratic drawing rooms, such as Madame de Staël's who was very active against slavery, and later in her daughter's, the duchess de Bröglie. A cosmopolitan and elegant congregation met regularly in the independent Chapelle Taitbout ; its financial support was to be decisive for protestant charities.
The Revival Movement also reached the provinces and rural areas. In the Alps Felix Neff was active in evangelization as well as education and economic development. The success of his work was widespread.
On one hand revivalists created communities often separated from reformed parishes and independent from the State. On the other hand they infiltrated Concordat-bound parishes in which they were present and active in a more discreet way. 19th century Church organisation gave each parish a lot of independence. Orthodox and liberals wanted Church and State to be linked, claiming that this would prevent small groups from taking over parishes and annexing them. Revival partisans favoured the separation of Church and State which, they said, would give them more facilities to develop their influence.
