Monasticism in Western Europe reached its zenith during the High Middle Ages of the late eleventh century and early twelfth century. Coming out of the ascetic tradition of the Desert Fathers at the end of the third century, monasticism grew to become a highly influential movement with centres of worship and learning throughout medieval Europe. In this paper I will describe the development of medieval monasticism and consider the spiritual benefits that it offered to men and women both inside and outside monastic communities. I will not provide a comprehensive analysis of the benefits. Instead I will look at examples from the spiritual disciplines of prayer, study and manual work. I will conclude with a reflection on what spiritual benefit monasticism might offer the life of the church today.
