Why did Jean-Jacques Rousseau convert to Roman Catholicism as a young man?

Jean-Jacques Rousseau converted to Roman Catholicism as a young man of 16 while he was in flight from his engraver’s apprenticeship in Geneva.21

His conversion was facilitated by the baroness de Warens, a Swiss aristocrat living in Savoy who had herself converted to Catholicism. Mme de Warens engaged in political espionage and worked as a missionary specializing in the conversion of young male Protestants, and Rousseau became one of her converts after seeking her protection.21

Rousseau later repudiated this conversion in 1754 when he returned to Geneva to seek readmission to the Calvinist church and recover his rights as a citizen.3
