Today is the Feast of St. Ansgar, often called the Apostle of the North; he is the patron saint of Denmark. He took
Isaiah 49:6 (cf. Acts
13:47) very literally, and set out to preach the message of Christ to the utmost ends of the earth -- in those days, Scandinavia. Medieval Sourcebook has a
Vita Ansgari, along with some hymns in his honor.
Notam facis incredulis,
Doctrinam evangelicam,
Lucem ministrans populis
Ducis in viam coelicam.
