62 Indisputably much has been done in this direction, especially after the publication of the Encyclicals Rerum Novarum and Quadragesimo Anno . We are happy to voice Our paternal approval of the zealous pastoral activity manifested by so many Bishops and priests who have with due prudence and caution been planning and applying new methods of apostolate more adapted to modern needs. But for the solution of our present problem, all this effort is still inadequate. When our country is in danger, everything not strictly necessary, everything not bearing directly on the urgent matter of unified defense, takes second place. So we must act in today's crisis. Every other enterprise, however attractive and helpful, must yield before the vital need of protecting the very foundation of the Faith and of Christian civilization. Let our parish priest, therefore, while providing of course for the normal needs of the Faithful, dedicate the better part of their endeavors and their zeal to winning back the laboring masses to Christ and to His Church. Let them work to infuse the Christian spirit into quarters where it is least at home. The willing response of the masses, and results far exceeding their expectations, will not fail to reward them for their strenuous pioneer labor. This has been and continues to be our experience in Rome and in other capitals, where zealous parish communities are being formed as new churches are built in the suburban districts, and real miracles are being worked in the conversion of people whose hostility to religion has been due solely to the fact that they did not know it.
