Also agree with tec.
Religion/ists (being physical, carnal, natural, temporal) is/are spiritually blind. As such it/they misconstrue almost everything, especially in this instance confession and repentance.
Confessing to religionists is actually insane since they are under the power of the "god of religion". They have no relationship with the "god of Abraham". They may know some facts about him, but they do not know him personally, and prevent others from knowing him and his son in an intimate relationship.
In general spirituality improves once God grants repentance (awareness of dysfunction) and faith (a wide opening of our spiritual eyes) after we have a favourable heart response to a hearing (or a pursuit) of the "good news ABOUT Jesus" which includes forgiveness of all our sins past, present and future as an unmerited free gift which deletes fear, guilt, embarassment and the legal power of sin or dysfunction in our lives (Rom 10:16,17).
