26 This does-not diminish his zeal. The true apostle must make himself "all things to all men" in order to save all. Like the Divine Redeemer, he ought to be moved with compassion, "seeing the crowds . . . bewildered and dejected, like sheep without a shepherd." By means of the printed and spoken word, by direct participation in the above-mentioned cases, he can labor on behalf of the people according to the principles of justice and charity by favoring and promoting those institutions which propose to protect the masses from the invasion of Socialism, saving them at the same time from both economic ruin and moral and religious chaos. In this way the assistance of the clergy in the works of Catholic Action has a truly religious purpose. It will then not be a hindrance, but rather a help, to the spiritual ministry by enlarging its sphere and multiplying its results.
