For today’s saint we go back to the Dark Ages, and to France, in the person of Saint Remigius:
Saint Remigius, Remy or Remi, (French: Saint Rémi or Saint Rémy; Italian: Remigio; Spanish: Remigio; Occitan: Romieg; Polish: Remigiusz; and Breton: Remig), was Bishop of Reims and Apostle of the Franks, (c. 437 – January 13, 533). On 24 December 496 he baptised Clovis I, King of the Franks. This baptism, leading to the conversion of the entire Frankish people to Nicene Christianity, was a momentous success for the Catholic Church and a seminal event in European history.
Remigius occupies an interesting time in the history of the Church. Rome had fallen, Christianity has emerged as the main religion of the remnants of the Roman Empire, and most of the early Fathers of the Church had already come and gone. At this point in time the faith was expanding past Roman borders (which it had done in the east earlier).
