This church was not dedicated to one of the many people who died as martyrs (witnesses to their faith) for their Christian beliefs, or whom we venerate as blessed or saints because of their exemplary lives. Rather, this parish has chosen God himself – in the "Holy Trinity" – as its patron saint. According to Christian doctrine, we believe in ONE God, who exists in THREE persons – God the Father, God the Son (Jesus Christ), and the Holy Spirit.
The following description can be found on the EKD (Evangelical Church in Germany) website:
+ “The word attempts to express the seemingly impossible, namely that God is simultaneously three and one. To understand this, it helps to consider how people have experienced God throughout history: as a Creator who loves his world and humanity like a father loves his children. As a God who himself became human in Jesus Christ, his Son, and shared human life. And finally, as a God who is still present and alive among people in the Holy Spirit.”
