Rights and responsibilities is the third of the seven key themes of Catholic social teaching. This theme says that every person has a fundamental right to life and to the necessities of life. In addition, every human has the right to what is required to live a full and decent life, things such as employment, health care, and education. The right to exercise religious freedom publicly and privately by individuals and institutions along with freedom of conscience need to be constantly defended. In a fundamental way, the right to free expression of religious beliefs protects all other rights.
