Many (if not most) Catholics think of the confessional somewhat akin to a torture chamber. They avoid it with the attitude of "why would anyone intentionally go there to harm themselves?" In truth, it is a place of grace, peace, and (true) empowerment. Yet, I know that many priests have not made it seem to be so. How do I know this? Because more people than I can count have told me that they had "bad experience" in the confessional years ago and have not been back to confession since then (i.e. they are admitting to being in a state of mortal sin). Thankfully, some say this when they are returning to the sacrament for the first time, but not all do (ever).
There is another group of Catholics who think of the confessional more like a dentist's chair: something they will do when they absolutely have to, but will avoid it until the very last minute. Usually those in this category are making this choice because just do not want to deal with their sins, and they are banking on the hope that they will go to confession the day before they die suddenly and unexpectedly (yeah, right!). These people already know that they need to go to confession, but they are hedging their bets. I am not writing to them; they know what they need to do, and they also know that they have no idea when they will be called to meet the Lord.
The first group of people--those who have willingly chosen to reject the one sacrament that grants us the full pardon and remission of our sins--is who I wish to speak to today. First off, let me say, "sorry". I apologize for every one of my brother priests who did anything that drove a child of God away from the forgiveness of God. I do not know their intentions (that is only between them and God), but I suspect that a good portion of them thought they were doing something good and right (regardless of how non-Catholic they were behaving). The liberalism that infected and poisoned many clergy who were ordained between the 70's and 90's caused them to think that it is a good thing to break the rules of the Church.
Secondly, I also want to apologize for those priests who went further than merely breaking some rules. I am speaking about those who committed a horrendous sin against someone in the confessional itself (I have heard a number of these stories as well). What they did was vile. There is no excuse for it (though it can be forgiven if they too repent), and if his Bishop did not properly discipline him, then I apologize for that Bishop as well. They both committed grave sin, and will have to give account for it someday before the judgment seat of Christ.
I will stop with the apologizing. I do not wish to get schmoozy. What you need to hear is that not every priest is like those mentioned above. No, they are not all "great confessors", but there are good priests who know what the rules are in the confessional, and they are willing to obey them. It may take some time to find them, but if you ask around to other Catholics you will find them; then go to them (frequently). Take advantage of the grace available to you in this wonderful sacrament; do not let a bitterness rule your life and keep you from God's grace.
Recognizing the difficulties that go along with searching for a good confessor, let me mention also the boundaries of a good and proper confession. I have people come and ask me, "Father, I just went to confession at St. Waldo's and Fr. Looseygoosey did it different from what I expected, was it a valid confession or do I need to go again?" Something can be "illicit" (rules broken) and still be "valid" (a genuine experience of the sacrament). The priest must actually hear your confession (he cannot be asleep); you must confess all known grave sins in kind and number; you must express genuine penitence; he must give you some kind of a penance; he must say an absolution (which is recognizable as an absolution--"bless you, now go" is not a valid absolution); you must follow through with performing the penance as soon as possible. There is a lot of latitude there, but those are the minimums; if something fell between the cracks, find another priest that will do it right.
Excuses are easy to find if we really do not want to do something, and I know it can be hard to want to go to confession. Leave behind all excuses; now. As times around us get more difficult, you are even less certain that you will have time to go back to confession before you go to meet your maker. Whatever you experienced, do not allow a foolish priest's mistakes (or a wicked priest's sins) to keep you from receiving God's grace. Christ gained it for you, and He wants you to have it. Confession is not optional, and if you really want to go to Heaven, God will provide a good priest for you; ask and you will find.
