The Process of Conversion

When a ruler marched his people to the waters of baptism, the work of Christianization had only begun. Christian kings could order their subjects to be baptized, married, and buried in Christian ceremonies, which ordinary people did increasingly across Europe. Churches could be built, and people could be required to attend services and belong to parishes, but the process of conversion was a gradual one.

How did missionaries and priests get masses of pagan and illiterate peoples to understand Christian ideals and teachings? They did it through preaching, assimilation of pagan customs, the ritual of penance, and veneration of the saints. Those who preached aimed to present the basic teachings of Christianity and strengthen the newly baptized in their faith through stories about the lives of Christ and the saints.

Deeply ingrained pagan customs and practices, however, could not be stamped out by words alone or even by imperial edicts. Thus Christian missionaries often pursued a policy of assimilation, easing the conversion of pagan men and women by stressing similarities between their customs and beliefs and those of Christianity. In the same way that classically trained scholars such as Jerome and Augustine blended Greco-Roman and Christian ideas, missionaries and converts mixed barbarian pagan ideas and practices with Christian ones. For example, bogs and lakes sacred to Germanic gods became associated with saints, as did various aspects of ordinary life, such as traveling, planting crops, and worrying about a sick child. Aspects of existing midwinter celebrations, which often centered on the return of the sun as the days became longer, were assimilated into celebrations of Christmas. Spring rituals involving eggs and rabbits (both symbols of fertility) were added to celebrations of Easter.

The ritual of penance was also instrumental in teaching people Christian ideas. Christianity taught that certain actions and thoughts were sins, meaning that they were against God’s commands. Only by confessing sins and asking forgiveness could a sinning believer be reconciled with God. Confession was initially a public ritual, but by the fifth century individual confession to a parish priest was more common. During this ritual the individual knelt before the priest, who questioned him or her about sins he or she might have committed. The priest then set a penance such as fasting or saying specific prayers to allow the person to atone for the sin. Penance gave new converts a sense of the behavior expected of Christians, encouraged the private examination of conscience, and offered relief from the burden of sinful deeds.

Although confession became mostly a private affair, most religious observances continued to be community matters, as they had been in the ancient world. People joined with family members, friends, and neighbors to celebrate baptisms and funerals, presided over by a priest.

Veneration of saints, people who had lived (or died) in a way that was spiritually heroic or noteworthy, was another way that Christians formed stronger connections with their religion. Saints were understood to provide protection and assistance to worshippers, and parish churches often housed saints’ relics, that is, bones, articles of clothing, or other objects associated with them. The relics served as links between the material world and the spiritual, and miracle stories about saints and their relics were an important part of Christian preaching and writing. (See “Listening to the Past: Gregory of Tours on the Veneration of Relics.”)

Christians came to venerate the saints as powerful and holy. They prayed to saints or to the Virgin Mary to intercede with God, or they simply asked the saints to assist and bless them. The entire village participated in processions marking saints’ days or important points in the agricultural year, often carrying images of saints or their relics around the houses and fields. The decision to adopt Christianity was often made first by an emperor or king, but actual conversion was a local matter, as people came to feel that the parish priest and the saints provided them with benefits in this world and the world to come.
