10 We have recalled these principles, which on other occasions We had already elucidated, in the hope that all dispute about the name of Christian Democracy will cease and that all suspicion of any danger coming from what the name signifies will be put at rest. And with reason do We hope so; for, neglecting the opinions of certain men whose views on the nature and efficacy of this kind of Christian Democracy are not free from exaggeration and from error, let no one condemn that zeal which, in accordance with the natural and divine laws, aims to make the condition of those who toil more tolerable; to enable them to obtain, little by little, those means by which they may provide for the future; to help them to practice in public and in private the duties which morality and religion inculcate; to aid them to feel that they are not animals but men, not heathens but Christians, and so to enable them to strive more zealously and more eagerly for the one thing which is necessary; viz., that ultimate good for which we are born into this world. This is the intention; this is the work of those who wish that the people should be animated by Christian sentiments and should be protected from the contamination of socialism which threatens them.
