Ways to implement the Christianization of Europe:
– missionary preachers (Saint Patrick in Ireland, Saint Boniface among the Germanic tribes, Saint Cyril and Methodius among the Slavs);
– Conversion to Christianity of monarchs and tribal leaders (often by force);
– wars under the pretext of converting heretics to the true faith (Charlemagne converted the population of the territories he conquered to Christianity under the auspices of the Pope).
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
