Still you are subject to Rome, yet content to remain under the protection of the British flag?

The Catholic Answers

Catholics are subject to the Bishop of Rome on questions of religion. But they are not subject to him in national affairs. This distinction naturally flows from the doctrine that the religion of Christ is not an affair of the British Empire, but for all men. Britishers should be Christians, but Christianity is not necessarily British. We Catholics are not so foolish as to confuse these two things. As Catholics and as citizens we are content to remain under the British flag, and to shed our blood in defending it. Why should we not be? We are not Italians, or Frenchmen, or Germans. And we have as much right to love our country and die for it, if necessary, as any other citizen.
