Christianity came to our region in Roman times.
Today, around 124,000 Roman Catholics, around 32,000 Protestant Christians and around 5,000 Christians who belong to other Christian churches/communities live in the city of Aachen.
In the Arbeitsgemeinschaft Christlicher Kirchen Aachen (ACK) "the churches and church communities of this area ... are united, which confess the one Lord Jesus Christ as God and Savior according to the Holy Scriptures and strive to fulfill his mission through word and witness for the glory of the triune God and for the salvation of the people of our time." (From the statutes of the Arbeitsgemeinschaft Christlicher Kirchen Aachen)
Membership of the Christian church is established through baptism. It is a sacrament that goes back to Jesus' command. The baptizer pours water over the person being baptized and says: "I baptize you in the name of the Father and of the Son and of the Holy Spirit".
The profession of faith
The creed, which was formulated by the first two general councils of Nicea (325) and Constantinople (381), is common to all the great churches of the East and the West.
"We believe in one God, the Father, the Almighty, who created all things, heaven and earth, the visible and invisible worlds. And in one Lord Jesus Christ, the only begotten Son of God, born of the Father before all time: God from God, light from light, true God from true God, begotten, not created, of one essence with the Father; through him all things were created. For us human beings and for our salvation he came down from heaven, took on flesh through the Holy Spirit from the Virgin Mary and became man. He was crucified for us under Pontius Pilate, suffered and was buried, rose again on the third day according to the Scriptures and ascended into heaven. He is seated at the right hand of the Father and will come again in glory to judge the living and the dead; there will be no end to his reign. We believe in the Holy Spirit, who is Lord and gives life, who proceeds from the Father*, who is worshipped and glorified with the Father and the Son, who spoke through the prophets, and the one, holy, catholic** and apostolic Church. We confess the one baptism for the forgiveness of sins. We await the resurrection of the dead and the life of the world to come. Amen."
(*) Since the Middle Ages, the churches of the Western tradition have added: "and the Son".
(**) This is meant in the original sense of the word, as all-encompassing, spanning the globe, not in the denominational sense. In some churches one says here "Christian" or "universal Christian".
