I try and commune every Sunday if at all possible.
In the Orthodox Church I belong which is part of the OCA (Orthodox Church In
America) we partake of 'Private' Confession & 'General Confession'.
Private Confession is a must during Lenten periods and major feast days when 'General Confession' is not available.
However, We also have 'General' Confession which is usually after Vespers on a Saturday when the priest announces it. The priest will come out from behind the Iconostasis and in front of the Icon of Christ recite a series of 'Forgiveness Prayers'. Then he will proceed with 'General Confession'.
At 'General Confession' the entire congregation kneels and
recites the following from the 'Full Confession of St. Demetrius of Rostov) Which goes-
"I confess to the Lord my God and before thee, venerable father, all my countless sins, committed by me unto this very day and hour, in deed, word or thought. I sin daily and hourly by mine ingratitude toward God for His Great and countless blessings and benevolent providence over me, a sinner.
I have sinned through: idle talking, judging others, stubborness, pride, hard-heartedness, envy, anger, slander, inattention, negeligence concerning my salvation, carelessness, indifference, impertinence, irritability, despondency, rendering evil for evil, bitterness, disobedience, complaining, self-justification, contradicting others, self-will, being reproachful, gossiping, lying, light-mindedness, tempting others, self-love, ambition, gourmandizing, eating and drinking to excess, vanity, laziness, entertaining
unclean thoughts, acquisitiveness, impure glances, absence from Divine Services, because of laziness and carelessness, absentmindedness at prayer both in church and at home; I have sinned in deed, word, thought, in sight, hearing, smell, taste, touch and the rest of my mental and physical senses; of all my sins I repent and beg forgiveness.
(At this point there is about a five minute silence. Here one should mention privately to God specifially any other sins which may be burdening the soul).
Forgive and absolve me, venerable father, and bless me to commune of the holy and life-creating Mysteries of Christ unto the remission of sins and life-everlasting."
At this point each individual person will go to the priest and receive absolution in the usuall manner.
In our parish approximately 75% - 85% of the people who go to Communion on any given Sunday do so every Sunday. Usually when there is a Liturgy during the week the priest will be there a half hour prior to the start of the Liturgy. If you
stand in front of the Iconostasis he will come out. He will ask if you have any sins to confess and proceed to give you confession and/or absolution (depending on how you reply). Our priest is very strict and knows his parishioners (even to the kind of car we drive). If you come up and he
knows you have not received confession or absolution he will not give you communion. We all know enough not to even attempt it!
On any given Sunday well over 75% or more of the congregation partake of communion which usually takes bout 15 to 20 minutes.
I also utilize the prayer of St Demetrius when I am preparing myself for private Confession. It reading through it, it helps we to see all my sins and weaknesses.
