Well, Catholics have 3 choices for the Penetential Rite in Mass (as you prolly know from your good Wiki linking) but my favorite has always been “Option A.”
Let me speak from my experience when I was a non-C:
I had always equated the “altar call” was the penitential rite in less “formal” Protestant churches, and the sinners prayer will usually have you say you’re sorry to the Lord:
The “Sinner’s Prayer” is a term that describes the words spoken by a person when he or she has recognized their sin and their need for a relationship with God through Jesus Christ. It goes something like this:
“Father, I know that I have broken your laws and my sins have separated me from you. I am truly sorry, and now I want to turn away from my past sinful life toward you. Please forgive me, and help me avoid sinning again. I believe that your son, Jesus Christ died for my sins, was resurrected from the dead, is alive, and hears my prayer. I invite Jesus to become the Lord of my life, to rule and reign in my heart from this day forward. Please send your Holy Spirit to help me obey You, and to do Your will for the rest of my life. In Jesus’ name I pray, Amen.”
(From here)
I’ve seen it done very dramatically (even at a funeral once), but I have never seen a whole congregation recite the prayer, so I guess it’s very personal – and might take a bit of courage – to go up to the pulpit/altar/stage and do this. To go up that way,
personally makes me think the person who is going up is either a) very humble or b) grandstanding.
Actually, I kept going to altar calls because I was literally missing the actual Sacrament of Confession. (Go figure, huh?) I felt like I needed to be forgiven again and again and keep dedicating my life over and over because I had “backslidden.”
Before I left and after I came home to the Church, I always felt very humbled during our
Confetior that we say, “…and I confess to Almighty God, and to you, my brothers and sisters…” and this line: “I ask you, my brothers and sisters, to pray for me to the Lord our God.”
It’s communal. We’re apologizing to God, and to each other. And we’re doing it together! It’s the most public type of “confession” I know, acknowledging our unworthiness just before the Eucharist. Man, I love that “Option A.” Feels better to me than any altar call I’ve done in my past.
