However, does anyone believe there is something "wrong" with confessing weekly?
I reply to you to add a consideration to the excellent replies already given by Pravoslavbob and Father George. That is why I isolated your first sentence above.
If we can look at "confessing" as a process, something that we do, it is clear that we confess at least once a week during Divine Liturgy:
"I believe, O Lord, and I confess that Thou art truly the Christ, the Son of the living God, Who came into the world to save sinners, of whom I am the first. Moreover, I believe that this is truly thine immaculate Body and that this is truly thy most precious Blood. Therefore, I pray Thee, have mercy upon me, and forgive my transgressions, both voluntary and involuntary, in word or in deed, in knowledge or in ignorance. And grant that I may partake of thy Holy Mysteries without condemnation, for the remission of sins and for life everlasting."
Daily, the Trisagion Prayers presuppose that when we pray for the Lord to forgive our sins we do not pray in an abstract fashion but are truly sorry for our real, concrete sins and that we promise that we will try to sin no more. I am highlighting the places that emphasize this.
"O heavenly King, O Comforter, the Spirit of truth, who art in all places and fillest all things; Treasury of good things and Giver of life: Come and dwell in us and cleanse us from every stain, and save our souls
, O gracious Lord.
Holy God, holy mighty, holy immortal: have mercy on us
. (Thrice)All-holy Trinity, have mercy on us. Lord, cleanse us from our sins. Master, pardon our iniquities. Holy God, visit and heal our infirmities for thy name's sake.Lord, have mercy.
Our Father, who art in heaven, hallowed be thy name; thy kingdom come; thy will be done on earth, as it is in heaven. Give us this day our daily bread; and forgive us our debts, as we forgive our debtors
; and lead us not into temptation, but deliver us from the evil one."
Also, the evening prayers may include the following:
"PSALM 50: Have mercy upon me, O God, according to thy great mercy: according to the multitude of thy tender mercies blot out mine iniquity. Wash me thoroughly from mine iniquity, and cleanse me from my sin. For I acknowledge mine iniquity: and my sin is ever before me. Against thee only have I sinned, and done evil in thy sight: that thou mightest be justified in thy words, and prevail when thou art judged..."
"A PRAYER OF REPENTANCE: O Lord our God, good and merciful, I acknowledge all my sins which I have committed every day of my life, in thought, word and deed; in body and soul alike. I am heartily sorry that I have ever offended thee, and I sincerely repent; with tears I humbly pray thee, O Lord: of thy mercy forgive me all my past transgressions and absolve me from them. I firmly resolve, with the help of Thy Grace, to amend my way of life and to sin no more; that I may walk in the way of the righteous and offer praise and glory to the Name of the Father, Son, and Holy Spirit. Amen.
SAINT EPHRAIM’S PRAYER:
O Lord and Master of my life, take from me the spirit of sloth, despair, lust of power, and idle talk.
But give rather the spirit of chastity, humility, patience, and love to Thy servant.
Yea, O Lord and King, grant me to see my own transgressions, and not to judge my brother, for blessed art Thou, unto ages of ages. Amen.
JESUS PRAYER: Lord Jesus Christ , Son of God, have mercy on me a sinner."
In addition, it seems to me that each time that we catch ourselves doing something bad or falling short, we have the opportunity (that we should take advantage of) to confess right then and there. One more thing, my Priest tells each penitent to hold nothing back because we are confessing to the Lord and He knows everything anyway. (I know I am paraphrasing but that's the way I remember this exhortation).
So, we confess to the Lord almost all of the time and we ask for forgiveness almost all of the time. The Holy Mystery of Penance (formal name but also called Confession and Reconciliation), is something that we do in addition, and rightly so. The issue is simply whether we MUST do so each and every time before we take communion. Now, if we take communion minimally, it is obvious that for some reason we have separated ourselves from the Church and must be reconciled. If our shortcoming is a grave sin or if we persist in falling short in a particular vice that we have, we should also avail ourselves of the Mystery of Penance. Each individual is different so it would be impossible to say how often one should receive the Sacrament of Confession. That is why the frequency is set between the spiritual father and ourselves. I want to reemphasize the critical role each one of us has in this process. We cannot abdicate our responsibility to confess, correct and partake all of the time by (a) leaving it all up to the priest, (b) observing the minimal requirements, or (c)playing a game before the priest and our fellow parishioners (We may succeed in fooling them, and ourselves, but there is no way that we are going to fool the Lord).
