An all too often forgotten immemorial Catholic practice is that of gaining or ʻwinningʻ indulgences.
In order to do what we can (while in this earthly life) to engage in reparation for the temporal punishment due to our sins we ought to know what indulgences are and the necessary conditions for gaining them.
What is an indulgence?
How do we gain indulgences? (Notes in Red our mine)
"The conditions for the winning of Indulgences are, in addition to the reception of Baptism and communion with the Church;
β) Subordination to the one granting the Indulgence;
γ) The habitual intention at least of gaining the Indulgence; (You have to INTEND to receive the specific indulgence)
δ) The exact performance of the prescribed works. Cf. CIC 925, 927; Suppl. 25, 2." (Ott, L. (1957). Fundamentals of Catholic dogma )
What types of indulgences are there?
* There are two types of indulgences. Partial and Plenary:
Partial - Partially remits from the temporal punishment due to sins
Plenary - Fully remits from the temporal punishment due to sins
* To acquire a plenary indulgence the following conditions are required:
1. Sacramental confession
2. Reception of the Blessed Sacrament
3. Prayer for the intention of the Sovereign Pontiff
4. Total detachment from sin, even venial sin.
Where can we look to see approved indulgences?
There is a manual of indulgences put out by the Supreme Tribunal Apostolic Penitentiary (Tribunal of the Roman Curia in charge the governance of indulgences) The manual is known as the ʻEnchiridion Indulgentiarumʻ.
