The Gospel of Mark, as the oldest gospel, serves as the foundation for what has been told about Jesus of Nazareth over the centuries. This commentary provides essential knowledge while also making the current state of research on the Gospel of Mark accessible. It aims to remain transparent about what is controversially discussed in research. Therefore, it refrains from clarifying ambiguous text passages. The translation brings even those without knowledge of Greek as close as possible to the Greek text, allowing readers to develop their own hypotheses and make discoveries about a text that emerged in a crisis situation. Challenging sections and gaps invite interpretation. The search for meaning remains with the readers.
