Sin is a mistake made by the individual, but there is the opportunity for spiritual growth and development. An act of penance ("epitemia"), if the spiritual guide requires it, is never formulaic, but rather is directed toward the individual and their particular problem, as a means of establishing a deeper understanding of the mistake made, and how to effect its cure. Because full participatory membership is granted to infants, it is not unusual for even small children to confess. Though the scope of their culpability is far less than an older child, they also have an opportunity for spiritual growth.
