We confess to priests because Jesus told the Apostles to go and handle the forgiveness of sins, not simply look to Heaven and have them forgiven. The Sacrament of Confession is remarkably powerful and humbling. Jesus knew what He was doing. You oughta try it sometime. It is not limited to Catholics, you know. :)
The help of all Christians is normally, well, helpful; examples abound in Scripture of those Christians who are to help others. We are told to pray for others; our prayers for the departed are heard by God.
Does that mean that saying the Rosary is required for salvation? No. That is like saying that one type of food is required to eat in order to live. But you must have SOME kind of food. Jesus has given us help aplenty along our Via. But it’s up to us to use that help.
Thanks, it's just that when I confess it is directly to God in prayer. I also find that powerful and humbling. I'm not sure how confessing to a good man could be an improvement on confessing directly to God.
