Abstract EN:

At the beginning of the ninth century, Jonas of Orleans, a bishop, wrote a treatise of Christian instruction meant for a married layman, Earl Matfrid. The last comprehensive edition of this work dates from the nineteenth century. It was made of three manuscripts, and did not include any critical works. But six new manuscripts were later brought to light and this led to the creation of new editions. Two versions of De institutione Laicali, based on two families of manuscripts, can be distinguished, which brings out two stages of writing. And Jonas seems to be the author of each. In his book, Jonas replaces the Christian layman within the theological scopes of Judgement and Salvation. According to him, Christian life means above all being ready to receive Holly blessing, which manifests itself through the sacraments. But it also consists in a permanent effort for purification achieved through prayer, moderate asceticism and virtuous actions: in others words, a kind of spirituality inspired by monastic life and ideals. However, Jonas also places different aspects of secular life at the heart of his work. As far as the domestic and conjugal spheres are concerned, he encourages stability in the couple and gives the husband and wife the task of raising their children as good Christians. And as far as the social sphere is concerned, he insists on respecting others’ dignity and exercising justice without personal interest.
