Although the canonization process remained unsuccessful, the worship of Hildegard has never stopped. In the Rupertsberg Monastery, the day of death of the founder was celebrated every year with the Hildegardis Festival to which many people from the region made a pilgrimage. In addition to the monasteries in Eibingen and on the Rupertsberg, also the partner monasteries such as Villers, Gembloux or St. Eucharius/St. Martin in Trier liturgically worshipped Hildegard.

On a precious antependium, a hanging for the altar, made from red silk and presumably produced around 1230 on the Rupertsberg, she is displayed as a Saint with a nimbus. Also in the nearby Eberbach Monastery in the Rheingau region, nobody doubted her sanctity. This is proven by a often-read scripture by the then Prior Geberno which originated between 1220 and 1224: In the Pentachronon sive speculum futurorum temporum, he called her „Saint Hildegard“.

The entry of her name in the Hagenau Manuscript of the Martyrology of Usuard (1412) and the Litany of the Saints of the Mainzer Agende [Agenda of Mainz; official church book] (1480), the first proven mentioning of Hildegard in a liturgical text of Mainz, was extremely important for her worship. In 1584, she was included in the Martyrologium Romanum (Roman Martyrology), an index of martyrs and saint of all countries, which in its importance was similar to a canonization.

The lack of liturgical texts proves that real worship by the people only took place at the actual places of work. In the 17th and 18th century, buildings and art works were created at these places, such as the monastery church of Eibingen finished in 1683, whose patrons were Rupert and Hildegard, as well as paintings, statutes and altarpieces showing her and Rupert.

After the convent in Eibingen was dissolved at the beginning of the 19th century, the worship of Saint Hildegard ceased. It is to the merit of the priests Ludwig Schneider and Adam Wagner from Eibingen and Bingen that the worship was revived again, starting at the previous monastery church in Eibingen and the Rochus Chapel in Bingen in the middle of the same century. The rediscovered worship of Hildegard of Bingen reached its peak with the foundation of the Abbey St. Hildegard above of Rüdesheim in 1904. This abbey is more active than ever, which is evidenced by the many pilgrims and visitors who contribute to the Hildegardis Festival each year. These are the church communities of Bingerbrück, Bingen, Eibingen and the Abbey St. Hildegard, which made Hildegard’s message accessible, as well as the Hildegard Forum of the Sisters of the Cross on the Rochusberg which is completely committed to bringing her message across.

The former local cult is now reaching far beyond the Bingen region: There are churches, monasteries, social institutions and schools everywhere bearing Hildegard’s name and it is not important at all that Hildegard is not an „official“ Saint.
