It is interesting for historians to note that the fraternity called for by Pope Francis in Fratelli Tutti was an idea abhorred by his predecessors in the 19th century. Fraternity, along with liberty and equality, had been demanded by the French revolutionaries in 1789, and had led to the slaughter of nuns and priests, an attempted genocide of the Catholic population of the Vendée, and the annihilation of the Church in France.
