Confession

In general, a confession is when a person tells someone a thing that the other person usually does not know. In different contexts, the word has slightly different meanings:

 In law, it is about telling a police officer or a lawyer about a crime. It might also about being a witness. In many law systems, people who confess a crime they committed will be punished less severely. 
 A confession of faith is usually when people say that they belong to a specific religious group or religion. This is usually done  as a ritual.
 In some Christian faiths, most notably, Roman Catholicism, Eastern Orthodox, and Oriental Orthodox Churches, a confession is telling a priest about one's own wrongdoing (which may be sinful).  In certain circumstances, the priest can then forgive the sinful behaviour.  Among the criteria are that the person who did wrong must be able to see that he or she did wrong, and they must be willing to correct the wrong to the best of their abilities.

Often, a confession is associated with an admission of a moral or legal wrong:

Not all confessions reveal wrongdoing, however. For example, a declaration of love is often considered positive both by the confessor and by the recipient of the confession and is a common theme in literature.Giulio Marra, Shakespeare and this "Imperfect" World: dramatic form and the nature of nowing (1997), p. 69, describing "the distinction between 'to do' and 'to confess', between having thoughts of love and confessing one's love, between the indetermination of a feeling and its final definition", as a theme that "creeps into the various stories".Charles Emil Kany, The Beginnings of the Epistolary Novel in France, Italy and Spain (1937), Volume 21, Issues 1-6, p. 19. 

There are several specific kinds of confessions that have significance beyond the social. A legal confession involves an admission of some wrongdoing that has a legal consequence. Confession in religion varies widely across various belief systems. It is usually part of a ritual by which the person acknowledges thoughts or actions considered sinful or morally wrong within the confines of the confessor's religion. In some religions, confession takes the form of an oral communication to another person. Socially, however, the term may refer to admissions that are neither legally nor religiously significant.Roger W. Shuy, The Language of Confession, Interrogation, and Deception (1998), p. 2–10.

Some confessions are very notable. For example, the confession of Henry II of England to the murder of Thomas Becket.
