This church is named after Remigius von Reims (* probably 436 in Laon; † January 13 or 15, 533 in Reims) was a bishop from the Gallo-Roman nobility in the east of what is now France. He became known through the baptism of the Merovingian king Clovis I and is venerated as one of the great saints of the Frankish people.
Remigius came from a wealthy family. He was called to be a bishop at the age of 22. After the conquest of his home region by Franks invading from the east, he successfully endeavored to integrate the new rulers into the late Roman tradition, both socially and religiously. In particular, he made it his task to Christianize the Franks for the Roman Church and to move them to turn away from Arianism, to which they partly adhered. He is therefore also referred to as the "Apostle of the Franks". He is also considered the founder of several dioceses in France.
Together with Queen Chlothilde, the wife of Clovis, Remigius is seen as a pioneer of Christianity in Europe. At Christmas just before the year 500 - there are sources that mention 497, 498 or 499 - he is said to have baptized Clovis and 3,000 more francs. While the bishop was performing this act, he said to the king: “Now bow down your head, proud Sicamber, and submit it to the gentle yoke of Christ! Worship what you have burned so far and burn what you have worshiped so far! "
