Third Scrutiny (Within Mass)

The scrutinies, which are solemnly celebrated on Sundays and are reinforced by an exorcism, are rites of self-searching and repentance and have above all a spiritual purpose. The scrutinies are meant to uncover, then heal all that is weak, defective, or sinful in the hearts of the elect; to bring out, then strengthen all that is upright, strong, and good. For the scrutinies are celebrated in order to deliver the elect from the power of sin and Satan, to protect them against temptation, and to give them strength in Christ, who is the way, the truth, and the life. These rites, therefore, should complete the conversion of the elect and deepen their resolve to hold fast to Christ and to carry out their decision to love God above all."

In order to inspire in the elect a desire for purification and redemption by Christ, three scrutinies are celebrated. By this means, first of all, the elect are instructed gradually about the mystery of sin, from which the whole world and every person longs to be delivered and thus saved from its present and future consequences. Second, their spirit is filled with Christ the Redeemer, who is the living water (gospel of the Samaritan woman in the first scrutiny), the light of the world (gospel of the man born blind in the second scrutiny), the resurrection and the life (gospel of Lazarus in the third scrutiny). From the first to the final scrutiny the elect should progress in their perception of sin and their desire for salvation.
