Which term refers to the acknowledgment of one's sins during Reconciliation?

The term that specifically refers to the acknowledgment of one's sins during Reconciliation is confession. Confession is a crucial aspect of the Sacrament of Reconciliation in the Catholic tradition, where individuals articulate their sins to a priest. This act not only involves admitting wrongdoing but also is a step towards seeking forgiveness and healing.

While contrition refers to the sincere remorse for having sinned, and penance involves the actions taken to demonstrate repentance after confession (such as prayers or acts of charity), absolution is the formal declaration by the priest that sins are forgiven. Each of these terms plays a significant role within the context of Reconciliation, but confession is distinctively about the process of acknowledging one's sins directly.
