Answer
Athanasius was known as "Athanasius Contra Mundum" ("Athanasius against the world"). This was because he was a strong advocate for the Nicene Creed, which declared that Jesus was both divine and human. This belief was opposed by many people at the time, including the Arians, who believed that Jesus was not divine. Athanasius was exiled several times for his beliefs, but he always returned to fight for them.
