The sacrament of Penance is one of the healing sacraments in the church. Here people are given an opportunity to confess their failing to the Lord through the priest representing the community.
Feeling the need for this sacrament is about us seeing ourselves as weak and all our failings having some affect on our relationships. As we confess our sins we are saying sorry to the community and promising to improve our lives by lessening the hurt we can sometimes cause to others.
Here also we need to let go of guilt and feeling sorry for ourselves if this is to be a real experience of healing. It is also called the sacrament of reconciliation, there are three parts in this reconciliation, the Lord, the community and the individual confessing his/her sins.
