THE USUAL CONDITIONS for gaining indulgences
Because the enemy has usurped our churches We commute the usual conditions required for gaining some indulgences as follows:
1. Instead of visiting a church, place yourself in the presence of God, as if you were in church and say the required prayers.
2. We commute the requirement of Confession for those who are unable to confess to an Examination of Conscience with an Act of Contrition and ten minutes meditation on the horrors of sin, which offends Almighty God.
3. We commute the requirement of Holy Communion to a Spiritual Communion with a prayer that the day, when we can again receive the Blessed Sacrament may come soon.
4. The intentions of the Supreme Pontiff are: the exaltation of Holy Mother Church, the extirpation (overcoming) of heresies, propagation of the Faith, the conversion of sinners and peace among Christian nations. Unless specific prayers are prescribed for the Pope's intentions, any vocal prayers may be used.
Requirements to gain an Indulgence
You may ask, "What must we do to gain an indulgence?" The first condition is,my brethren, that you should be in the state of grace; secondly, you must do the works and say the prayers authorized by the Holy Father, and have no inclination to any, no even willful venial sin. This is all that is necessary, and you must admit that our good Mother Church has certainly made it easy for her children to make use of this precious means of salvation., The Cure of Ars, Saint John Vianney. For instance, the condition for gaining a plenary indulgence presents the difficulty that to gain it in full a person must be free from all affection to venial sin., Saint Joseph Cafasso.
