Reconciliation becomes necessary because there has been the break of sin from which derive all the other forms of break within man and about him. Reconciliation, therefore, in order to be complete necessarily requires liberation from sin, which is to be rejected in its deepest roots. Thus a close internal link unites conversion and reconciliation. It is impossible to split these two realities or to speak of one and say nothing of the other.
It is this reconciliation, the result of conversion, which is dealt with in the present apostolic exhortation. For, as happened at the end of the three previous assemblies of the synod, this time too the fathers who had taken part presented the conclusions of the synod's work to the bishop of Rome, the universal pastor of the church and the head of the College of Bishops, in his capacity as president of the synod. I accepted as a serious and welcome duty of my ministry the task of drawing from the enormous abundance of the synod in order to offer to the people of God, as the fruit of the same synod, a doctrinal and pastoral message on the subject of penance and reconciliation.
In the first part I shall speak of the church in the carrying out of her mission of reconciliation, in the work of the conversion of hearts in order to bring about a renewed embrace between man and God, man and his brother, man and the whole of creation. In the second part there will be indicated the radical cause of all wounds and divisions between people, and in the first place between people and God: namely sin. Afterward I shall indicate the means that enable the church to promote and encourage full reconciliation between people and God and, as a consequence, of people with one another.
