The collect for today, the Feast of Saint Remigius (c. 438-533), Bishop of Rheims, Apostle to the Franks (source):
O God, who by the teaching of thy faithful servant and bishop Remigius didst turn the nation of the Franks from vain idolatry to the worship of thee, the true and living God, in the fullness of the catholic faith; Grant that we who glory in the name of Christian may show forth our faith in worthy deeds; through Jesus Christ our Lord, who liveth and reigneth with thee and the Holy Spirit, one God, for ever and ever.
Remigius was consecrated bishop of Rheims at age 22. The pagan Clovis I, who had married the Christian princess Clothilde, began his reign as king of the Franks about 20 years later, in 481.
Before entering combat against German tribes at Tolbiac, Clovis prayed to “Clothilde’s God” for victory. His soldiers won the battle, and Clothilde asked Remigius to teach the king about Christianity. Clovis was amazed by the story of “this unarmed God who was not of the race of Thor or Odin”. In the words of Remigius, the king came “to adore what he had burnt and to burn what he had adored”.
In 496, Remigius baptised Clovis in a public ceremony at Rheims Cathedral. Three thousand Franks also became Christians. Under the king’s protection, Remigius was able to spread the gospel and build churches throughout Gaul.
