The apostolic letter written at the close of the Great Jubilee of the Year 2000, given as the Holy Door of Saint Peter's was sealed. It looks back on the graces of the Jubilee, contemplates the face of Christ crucified and risen, and then sets a programme for the new millennium that is not a new strategy but holiness: 'Duc in altum', put out into the deep. It calls for a genuine training in prayer, Sunday Eucharist, the sacrament of Reconciliation, the primacy of grace, listening to the word and proclaiming it, and for a spirituality of communion lived in concrete charity toward the poor.
