Random Quote

“As often as possible they gathered together the children of the village and sat them down in the cabin. Father Brébeuf would put on a surplice and biretta and chant the Our Father, which Father Daniel had translated into Huron rhymes, and the children would chant it after him. Next, he taught them the sign of the cross, the Hail Mary, the Apostles’ Creed, and the Commandments.”

— Biography of St. Jean de Brébeuf
