The headquarters in Paris were moved from the modest rooms in the Rue Taranne to the large halls near the Boulevard des Italiens. Enfantin and Amand Bazard were proclaimed "Pères Suprêmes" ("Supreme Fathers") – a union which was, however, only nominal, as a divergence was already manifest. Bazard, who concentrated on organizing the group, had devoted himself to political reform, while Enfantin, who favoured teaching and preaching, dedicated his time to social and moral change. The antagonism was widened by Enfantin's announcement of his theory of the relation of man and woman, which would substitute a system of "free love" for the "tyranny of marriage".
