Bl. Pope Eugene III, Quantum praedecessores, Dec 1, 1145: “Bishop Eugene, servant of the servants of God, to his most beloved son in Christ, Louis, the illustrious king of the French, and to his beloved sons, the princes, and to all the faithful ones of God who are established throughout Gaul,-greeting and apostolic benediction.How much our predecessors the Roman pontiffs did labour for the deliverance of the oriental church, we have learned from the accounts of the ancients and have found it written in their acts. For our predecessor of blessed memory, pope Urban, did sound, as it were, a celestial trump and did take care to arouse for its deliverance the sons of the holy Roman church from the different parts of the earth. At his voice, indeed, those beyond the mountain and especially the bravest and strongest warriors of the French kingdom, and also those of Italy, inflamed by the ardour of love did come together, and, congregating a very great army, not without much shedding of their own blood, the divine aid being with them, did free from the filth of the pagans that city where our Saviour willed to suffer for us, and where He left His glorious sepulchre to us as a memorial of His passion, -and many others which, avoiding prolixity, we refrain from mentioning.”
