Regularly going to confession is a way to grow in holiness.
An Examination of Conscience is helpful in preparing for confessing one’s sins in the sacrament of Penance and Reconciliation. It helps one to reflect over several areas of one’s life and what he or she has done and if he or she has offended God in any way.
The sacraments are all instituted by Christ and can be found in the Bible. However, the way that these sacraments are to be conveyed is not necessarily in the Bible.
What is the purpose of the sacrament? If someone was baptized why do they need to be reconciled to God? This question poses some serious responses and these responses are not short. Fortunately, Jesus left the Catholic Church with an answer.
