Abbot Erpos Abtat, the first golden age of Kloosterrade

Following the death of Abbot Richer in 1122, a period of internal tensions and unrest at the administrative level began in Kloosterrade. Due to disagreements, the canons failed to elect a superior from among their own ranks. It is likely that there was a lack of strong personalities suited for the office of abbot, or perhaps the zeal with which one or another offered himself as the new superior was perceived as a threat to solidarity. On up to four occasions, clerics from outside the abbey were elected as superiors. However, all these elections were always controversial and repeatedly proved disappointing. Conflicts arising from differences of opinion regarding the interpretation of the monastic rule or from attempts to adapt monastic customs to stricter rules led to the superiors being removed from office by the bishop or the pope, or to their deciding to leave the abbey themselves. In 1134, Borno was elected abbot for the second time. He had been elected ten years earlier and had sought at that time to expand the choir’s prayer services. This attempt met with fierce resistance, and none other than the Pope decided that the old customs should be maintained. Thus, Borno had no choice but to leave Kloosterrade. With his return, the internal dissent subsided. A significant and crucial step toward the internal consolidation of the monastic community was the decision made by the canons in 1137 following Borno’s death. From then on, they would elect abbots only from within their own community, preferably fellow monks who had taught at the monastery school and had been raised in monastic discipline from childhood.

With Erpo, a native of Maastricht, Kloosterrade gained an abbot in 1141 who had been educated at the abbey from childhood. His long tenure as abbot lasted at least until 1178 and served as a stabilizing force. It is not without reason that this period is referred to in historical accounts as the golden age of medieval Kloosterrade. For decades, economic prosperity, piety, scholarship, and spirituality prevailed. Now the Consuetudines—the rules and customs introduced by Abbot Richer of Rottenbuch and later modeled after the Springiersbach monastery—received their final seal of approval, marking the completion of the development into a convent guided by a moderate ordo novus. In some respects, Erpo left his mark on the stricter observance of the monastic rule. By abolishing the use of fat in all meals, he enforced the strict dietary habits for which Abbot Richer—who had banned the consumption of meat—had set the tone. He also introduced the Silentium, a period of silence during which he literally forbade the canons from speaking outside of the liturgical hours of the Divine Office. On the other hand, Erpo believed that the celebration of the Divine Office “per diem et noctem,” in which the services of the Divine Office lasted almost uninterrupted from midnight to midnight, overburdened the canons. In addition to tightening the rule of life he had imposed, he therefore simplified the overloaded liturgical program. He limited the daily choral prayers to the actual hours and eliminated extras such as the recitation of the separate Office of the Blessed Virgin Mary and the singing of the 15 psalms before Matins and the seven penitential psalms before the prima hora. With these adjustments to the observance of the precepts and the structure of the choral prayer, the development of Kloosterrade under Abbot Erpo reached its conclusion. Thus, after only half a century, the abbey reached its zenith: Kloosterrade was the first community between the Rhine and the Scheldt to live according to the new guidelines of the Augustinian Rule and enjoyed supraregional renown due to the uniqueness of its Consuetudines. For other Augustinian monasteries seeking reform, Kloosterrade served as a model.

A defining feature of Kloosterrade Abbey in the 12th century and the first half of the 13th century was its status as a double monastery. With the arrival of the ministerial Embrico, his wife Adeleida, and their children Heriman and Margareta, a community of nuns was established alongside the men’s monastery. This development did not align with the founder Ailbertus’s vision. In 1140, the prior Johan succeeded in finding accommodation for the sisters outside the walls of Kloosterrade. However, Abbot Erpo readmitted women; he found a compelling justification for his decision in the necessity that female members of the order be able to perform all kinds of domestic duties. In the following decades, however, the influx of monks was much greater than expected, and the problem of an undesirable mixed community arose once again. It was not until 1243, with the nuns’ relocation to the Sinnich monastery newly founded by Abbot Marsilius, that the status of the double monastery came to an end.

The practice of pastoral care was equally undesirable and incompatible with the ideal of an ascetic and contemplative monastic life that the abbey had originally sought to achieve. Abbot Erpo’s predecessor, the Prior Johan, broke with this stance in 1140 when he decided to take over pastoral care in the parish and to accept the service of the church in Kerkrade by canons of the abbey. Toward the end of Erpo’s term, Kloosterrade acquired the patronage rights to several parish churches. The abbey’s sphere of influence thus expanded considerably between the Meuse and the Rhine.

A tangible testament to the abbey’s heyday is the monastic chronicle, which was written around 1160 during Erpo’s tenure as abbot. The medieval manuscript, which bears neither a title nor an inscription, was written by three unknown chroniclers and belongs to the genre of narrationes fundationis. It recounts the history of a monastery’s founding, the life of its founder, and, in most cases, its subsequent history. Such chronicles were composed with great care and attention in the abbey or monastery scriptorium, often by anonymous monks of the second generation. The Annales Rodenses recount the life story of Ailbertus, his upbringing and education in Tournai, and his search for a place where he could live as a hermit. The chronicle then tells the story of the abbey’s first five decades, from Ailbertus’s arrival in 1104 to the last entry from 1157. The manuscript owes the name Annales Rodenses, by which it is known to this day, to the canon Nicolaas Heyendal, who wrote a continuation of the history of Kloosterrade toward the end of the seventeenth century. The importance of the Kloosterrade chronicle for historiography is demonstrated by the fact that data from the period after 1157 are extremely scarce. Other sources from which the events and fortunes of the abbey in the late Middle Ages can be deduced are limited to a few surviving documents.

Abbot Erpo also succeeded in bestowing material prestige upon Kloosterrade. This is attested to by no fewer than 16 charters dating from 1141 to 1177, which record donations and purchases of land as well as the acquisition of rights to revenues. By the end of Erpo’s tenure, presumably in 1178, the abbey’s holdings had reached 3,570 hectares. Although nearly half of this was derived from donations or acquired by incoming monks, more than a fifth of the land was acquired by Abbot Erpo. The expansion of the lands is an indication of the abbey’s prosperity at that time. After 1178, the growth of the land holdings stagnated; the abbey’s income thereafter consisted mainly of interest and taxes. During the period of decline following the Limburg War of Succession and in later times, particularly in the 16th century, the abbey was forced by financial necessity to sell a considerable portion of its holdings to finance the costs of repairing the damage to church and monastery buildings caused by wars and looting.

It is not known when Abbot Erpo died. His successor, Abbot Rutger, is first mentioned in 1186 as abbot of Kloosterrade. He then served as a witness to the donation made by Duke Henry III of Limburg to Floreffe Abbey, as evidenced by the charter confirming this donation.
