‘Usual Conditions’ to obtain a Plenary Indulgence?
A plenary indulgence, according to the Catechism of the Catholic Church, remits all temporal punishment due to sin. To obtain the indulgence, a faithful Christian must be completely detached from all sin and fulfill the ordinary conditions of an indulgence, which are sacramental confession, reception of the Eucharist, and prayer for the intentions of the pope.
The Pope’s intention always includes the following objects:
i. The progress of the Faith and triumph of the Church.
ii. Peace and union among Christian Princes and Rulers.
iii. The conversion of sinners.
iv. The uprooting of heresy. Raccolta, 23
