7 We see that you are also worthy of praise for this reason. In the daily and prolonged trials in which you find yourselves, you follow only the just way when you give, as becomes Christians, respectful homage to your public authorities in the field of their competency. Moved by love of your country, you are ready to fulfill all your duties as citizens. But it is also a great consolation for Us to know that when the occasion has arisen, you have openly affirmed, and still affirm, that you can in no way stray from the precepts of the Catholic religion and that you can in no way deny your Creator and Redeemer, for Whose love many of you have faced torture and prison.
