The answer to this question can be found in Chapter 5, which is when Daniel visits Joel at his house in Capernaum for the first time. Daniel is shocked at the way that he sees so much evidence of Roman power in this city, and how the Jews seemingly do nothing but yield to that power, and are treated as if they were slaves. He therefore is increasingly angered at Joel's attitude towards the Roman occupation. When Hezron, Joel's father, expresses thanks for the synagogue that the Romans built, Daniel's rage overpowers him:
"A Roman synagogue!" he growled. "Raised with Roman taxes. What is it better than the stadium?"
Daniel clearly dislikes the syngogue in Capernaum because he sees that it is a product of the Romans, who keep him and his people in captivity. As a result, he thinks it is no better than the stadium where gladiators die for the amusement of the public. To him, having a synagogue built by the Romans desecrates his faith and his identity as a Jew. Hezron, however, does not share this idea.
