A Catholic Social Teaching message from Pope Paul VI: "If you want Peace, work for Justice."
... While the Church is proclaiming the kingdom of God and building it up, she is establishing herself in the midst of the world as the sign and instrument of this kingdom which is and which is to come.
Many Christians are drawn to give authentic witness on behalf of justice by various modes of action for justice, action inspired by love in accordance with the grace which they have received from God.
The teaching and spreading of her social doctrine are part of the Church’s evangelising mission. And since it is a doctrine aimed at guiding people’s behaviour, it consequently gives rise to a ‘commitment to justice,’ ...

This council exhorts Christians, as citizens of two cities, to strive to discharge their earthly duties conscientiously and in response to the gospel spirit. ...

... The experience of the past and of our own time demonstrates that justice alone is not enough, that it can even lead to the negation and destruction of itself, if that deeper power, which is love, is not allowed to shape life in its various dimensions.
... this council lays stress on reverence for all; everyone must consider every neighbour without exception as another self, taking into account first of all life and the means necessary to living it with dignity, so as not to imitate the rich man who had no concern for the poor man Lazarus.
