The parish church in Straelen was consecrated to the two saints Peter and Paul (Peter and Paul), also known as the "Princes of the Apostles". Their common feast day in the calendar of saints is June 29th.
* Simon, nicknamed Peter (rock), was a fisherman on the Sea of Genesareth when he – together with his brother Andrew – was called by Jesus Christ to be the "fisher of men". According to Catholic understanding, he is the supreme apostle, and the two millennia-long line of popes – currently Francis – are his successors. On statues and paintings Peter is almost always depicted with two keys in his hand, this attribute refers to the Bible passage in Matthew: “I will give you the keys of the kingdom of heaven; what you bind on earth will be bound in heaven, and what you loose on earth will be loosed in heaven” (chapter 16, verse 19).
* Paul was initially an opponent of the Christian movement and was not called to the apostle ministry like the other apostles by Jesus Christ during his lifetime, but was converted later with the famous "Damascus experience". His attribute is the sword with which he was executed. According to the Roman law of the time, such a sentence was a “privilege” (rapid death and not associated with a long, agonizing agony like other types of execution) that the citizens of Rome were entitled to.
