Pope Francis has asked that everyone be capable of making a pilgrimage through a Holy Door and receive the Jubilee Indulgence.
In his apostolic constitution on indulgences, Pope Paul VI: ‘an indulgence is a remission before God of the temporal punishment due to sins whose guilt has already been forgiven, which the faithful Christian who is dulydisposed, gains under certain defined conditions through the Church’s help when, as a minister of redemption, she dispenses and applies with authority the treasury of the satisfactions won by Christ and the saints.’ (Indulgentiarum Doctrina 1).
the Church promises that if certain conditions are met to show the Christian’s penitential intentions, they will receive the gift of a a Plenary or a full indulgence, which means, the Christian is freed from all temporal punishment due as a result of sins which have already been forgiven. The faithful can gain indulgences for themselves or apply them to the dead.
