Translation of the Gospel of St. Matthew
At that time, the Pharisees went and consulted among themselves, how to ensnare Jesus in His speech. And they sent to Him their disciples, with the Herodians, saying: Master, we know that Thou art a true speaker, and teach the way of God in truth, neither care Thou for any man, for Thou dost not regard the person of men. Tell us therefore, what dost Thou think? Is it lawful to give tribute to Caesar, or not? But Jesus knowing their wickedness, said: Why do you tempt Me, ye hypocrites? Show me the coin of the tribute. And they offered Him a penny. And Jesus saith to them: Whose image and superscription is this? They say to Him: Caesar’s. The He saith to them: Render therefore to Caesar the things that are Caesar’s, and to God the things that are God’s.

Civil and Political Responsibility of Catholics
Christ has come to save the real, concrete man who lives in history and in the community, and so Christianity and the Church have had a public dimension and value from the beginning.
As I wrote in the Encyclical Deus Caritas Est (cf. nn. 28-29) on the relationship between religion and politics, Jesus Christ brought a substantial novelty, opening the way towards a more human, freer world through the reciprocal distinction and autonomy of the State and the Church, that is, between what belongs to Caesar and what belongs to God (cf. Mt 22:21).
..[The Church] has a profound interest in the good of the political community, whose soul is justice, and offers it her specific contribution at a double level.
Indeed, Christian faith purifies reason and helps it to be better: as a result, with its social doctrine whose argument begins from what is conformed to the nature of every human being, the Church’s contribution is to enable whatever is just to be effectively recognized and then also accomplished. To this end, moral and spiritual energies are clearly indispensable as they ensure that the demands of justice are put before personal interests, a social category or even a State. For the Church, here again, there is ample space to root these energies in the conscience, to nourish them and fortify them.

Martin Archer Shee, cir. 1825-30
The immediate duty to act in the political sphere to build a just order in society is not the Church’s task as such, but that of the lay faithful, who work as citizens under their own responsibility. This is a duty of great importance to which lay Christians are called to dedicate themselves with generosity and courage, illuminated by faith and by the Magisterium of the Church and animated by the charity of Christ.
Special attention and extraordinary commitment are demanded today by those great challenges that endanger vast portions of the human family: war and terrorism, hunger and thirst, some terrible epidemics. But it is also necessary to face, with equal determination and clear policies the risks of political and legislative choices that contradict fundamental values and anthropological principles and ethics rooted in the nature of the human being, in particular, regarding the guardianship of human life in all its stages, from conception to natural death, and to the promotion of the family founded on marriage, avoiding the introduction in the public order of other forms of union that would contribute to destablizing it, obscuring its particular character and its irreplaceable role in society.
A Message From Pope Benedict XVI’s “Homily for Holy Mass for the New Evangelization,” Oct. 16th, 2011
Let us now reflect on the Gospel passage. It is the text about the legitimacy of the tribute to be paid to Caesar which contains Jesus’ famous answer: render therefore to Caesar the things that are Caesar’s, and to God the things that are God’s (Matt 22:21). But, before reaching this point there is a passage that can be applied to those who have the mission of evangelizing. Indeed, those who are speaking with Jesus — disciples of the Pharisees and the Herodians — compliment him, saying we know that you are true, and teach the way of God truthfully, and care for no man (Matt 22:16). It is this affirmation itself, although it is prompted by hypocrisy, that must attract our attention. The disciples of the Pharisees and Herodians do not believe in what they say. They are only affirming it as a captatio benevolentiae to make people listen to them, but their heart is far from that truth; indeed, they want to lure Jesus into a trap to be able to accuse him. For us, instead, those words are precious: indeed, Jesus is true and teaches the way of God according to the truth, and stands in awe of none. He himself is that “way of God”, which we are called to take. Here we may recall the words of Jesus himself in John’s Gospel: I am the way, the truth, and the life (John 14:6).

A brief reflection on the central question of the tribute to Caesar. Jesus replies with a surprising political realism, linked to the theocentrism of the prophetic tradition. The tribute to Caesar must be paid because his image is on the coin; but the human being, every person, carries in him- or herself another image, that of God, and therefore it is to him and to him alone that each one owes his or her existence. The Fathers of the Church, drawing inspiration from the fact that Jesus was referring to the image of the Emperor impressed on the coin of the tribute, interpreted this passage in the light of the fundamental concept of the human being as an image of God, contained in the first chapter of the Book of Genesis.
An anonymous author wrote: The image of God is not impressed on gold, but on the human race. Caesar’s coin is gold, God’s coin is humanity…. Therefore give your riches to Caesar but keep for God the unique innocence of your conscience, where God is contemplated…. Caesar, in fact, asked that his image be on every coin, but God chose man, whom he created to reflect his glory (Anonymous, Incomplete Work on Matthew, Homily 42). And St. Augustine used this reference several times in his homilies: “If Caesar reclaims his own image impressed on the coin”, he says, will not God demand from man the divine image sculpted within him? (En. Ps., 94:2). And further, as the tribute money is rendered to him [Caesar], so should the soul be rendered to God, illumined and stamped with the light of his countenance (ibid., 4:8).
This word of Jesus is rich in anthropological content and it cannot be reduced only to the political context. The Church, therefore, is not limited to reminding human beings of the right distinction between the sphere of Caesar’s authority and that of God, between the political and religious contexts. The mission of the Church, like that of Christ, is essentially to speak of God, to remember his sovereignty, to remind all, especially Christians who have lost their own identity, of the right of God to what belongs to him, that is, our life.
