This research study focused on providing insights to the Catholic Church on how well Catholics understand well-defined Catholic terms, and to know what the words she currently employs actually mean in the vocabulary of those who listen to her, and if that meaning does not overlap with the Church's definition of that word or term, what alternate term would do so. A list of the core Catholic Social Doctrine phrases, principles and thoughts we tested for in our research: 1.

The role of Truth in Society: A free society must affirm some truths as absolute. 16. Wages: Wages should be sufficient for families to support themselves and also save something.
