According to some authors,[who?] the issuing of the Edict of Milan,[25] showed that Constantine continued the policy of toleration that Galerius had established.[citation needed] He "continued to pay his public honors to the Sun", until 325, on coins that showed him jointly with Sol Invictus, whereas his later coins showed the Chi-Rho sign.[26] In that year he had the Christian Bishops convene at the First Council of Nicaea, and from then on continued to take an active interest in the affairs of the Church.
