St. Catherine's Church Oppenheim

In the course of the efforts of the Archbishop of Mainz to gain a foothold in Oppenheim, he and the Neustadt, which already belonged to the diocese of Mainz, also claimed the right of patronage over the recently completed St. Catherine's Church, which was previously looked after by the pastor of St. Sebastian. King Richard of Cornwall separated the two churches in 1258 and laid the diocesan borders of Mainz and Worms right through the city. The Katharinenkirche became Mainz and the parish church of the new town of Mainz. The Sebastianskirche fell to the diocese of Worms and remained the parish church of the old town of Worms.

In 1317 the Archbishop of Mainz had a pen at the Katharinenkirche, d. H. the facility was assigned to a community of clergymen who had to hold regular services (collegiate foundation). After 1400 the canons added their own choir in the west (consecrated in 1439). The Katharinenkirche had been a Lutheran parish church since 1556 and a Reformed parish church in Oppenheim since 1565. After the Peace of Westphalia in 1648, the church was finally handed over to the Reformed, until it served as a common house of worship for the Union Lutherans and Reformed from 1822.

The impressive St. Catherine's Church is the largest Gothic church between Strasbourg and Cologne. A true landmark that can be seen enthroned from many kilometers away over the Rhine slope. Particularly beautiful are the church windows created by the Frankfurt glass painter Alexander Linnemann in 1879, which shine in many colors when the sunlight falls.

Christian Miks from the Roman-Germanic Central Museum in Mainz and Marion Witteyer from the Directorate General for Cultural Heritage (GDKE) in Mainz describe the role the Romans played in the spread of Christianity:
