30 I recalled the people, and yet I did not escape their ill-will, which ill-will, however, I think we ought rather to tempt than fear. For why should we fear for the Name of Christ? Unless perchance I ought to be troubled because they say: “Ought not the Emperor to have one basilica, to which to go, and Ambrose wants to have more power than the Emperor, and so refuses to the Emperor the opportunity of going forth to church?” When they say this, they desire to lay hold of my words, as did the Jews who tried Christ with cunning words, saying: “Master, is it lawful to give tribute to Cæsar or not?” Is ill-will always stirred up against the servants of God on Cæsar's account, and does impiety make use of this with a view to starting a slander, so as to shelter itself under the imperial name? And can they say that they do not share in the sacrilege of those whose advice they follow?
