Are Catholics Wholly Pacifist?
Catholic Social Teaching includes many examples on the subject of justice and peace:

Pope John XXIII
- In 1963, Pope John XXIII wrote the encyclical (a letter sent by the Pope to the bishops of the Roman Catholic Church) Pacem in Terris.
- It starts with the words, “Peace on earth...cannot be firmly established unless the order which God laid down is dutifully observed.”
- Pope John also spoke out against the proliferation of nuclear weapons.

Pope Paul VI
- In 1967, Pope Paul VI said in his encyclical Populorum Progressio that promoting mutual solidarity and social justice are moral duties.

Pope Francis
- Pope Francis said that peace firstly means there are no wars, but it also means that every day a step ahead is made for justice. (Audience with children of the Peace Factory 2015.)

Catholic Just War Theory
- However, the Catholic Church is not a wholly pacifist religion and supports a Just War Theory. Some of the requirements for this theory were taught by Thomas Aquinas in the 13th Century:
- The war must be waged by a legitimate authority.
- It must be a last resort.
- It must be for a good purpose (e.g. justice and greater peace).
- It must be conducted in the right way, avoiding civilian casualties.
