This contribution begins with the affirmation of Saint Alfonso M. de Liguori «the task of the confessor is an office of charity, instituted by the Redeemer only for the good of souls». It reflects on some dimensions of the continuous formation of confessors, which is first of all a father, a teacher, then a doctor and finally the judge.

The Author presents the main indications of the post-Conciliar magisterium on the theme of formation and offers various elements of reflection in response to the ever new and delicate situations that our consciences are confronted with.

In light of the magisterial indications, and without wanting to fall into the case history, the Author tries to reflect on some concrete pastoral cases by emphasizing two unavoidable aspects: the intangibility of the sacramental seal and mature paternity in the administration of God’s mercy.
