Wiro of Roermond

Between 746 and 747, Wiro was one of eight bishops, along with St. Boniface, who wrote a letter to Æthelbald, King of Mercia, to reprove him for various dissolute and irreligious acts including stealing ecclesiastical revenue, violating church privileges, imposing forced labour on the clergy and fornicating with nuns.

[2] The letter implored Æthelbald to take a wife and abandon the sin of lust:We therefore, beloved son, beseech Your Grace by Christ the son of God and by His coming and by His kingdom, that if it is true that you are continuing in this vice you will amend your life by penitence, purify yourself, and bear in mind how vile a thing it is through lust to change the image of God created in you into the image and likeness of a vicious demon.

Remember that you were made king and ruler over many not by your own merits but by the abounding grace of God, and now you are making yourself by your own lust the slave of an evil spirit.

[3]Wiro was an itinerant missionary and preached in the region of the Maas and the Rhine, where his legend associates him with the priest Plechelm and the deacon Otger.

[4] Later, he founded St. Peter's Abbey on land given to him by Pippin II in the present Sint Odilienberg[5] near Roermond in the Netherlands with Otger.
