A few questions here...
What makes these holy men or clergy members any closer to God than you?
Why is it that they can commune or communicate with God better than you?
Are these intermediaries necessary in your religion? Why?
If you have such intermediaries but don't feel they are necessary, do you use them? Why or why not?
In my LDS faith...
Every local congregation (ward) has a bishop. The bishop did not choose that position or vocation. He was called by the Lord, through the Stake President, to serve. He is then ordained a bishop. He continues to be employed in his own profession. He serves usually for about 5 years and then someone else is called. Here are what I consider to be important points in answer to your questions...
1. Because the bishop was called of God and has certain priesthood keys, he is the one God wants to help congregation members in specific ways. There are some things that only he is authorized to do.
2. This calling in no way means that the bishop is necessarily closer to God than any member of his congregation. He has his own problems and challenges in life. But bishops take their responsibility seriously and I think most men, when called as bishops, really try to be close to the Lord. They know that they need to receive inspiration and a few hundred church members now count on them to be in tune with God.
3. LDS church members are expected to confess "serious" sins to their bishop. This is done face to face in the bishop's office or somewhere else.
4. Because the bishop was called of God and holds the necessary priesthood keys, and not because he is necesarily closer to God, God gives the bishop the inspiration he needs to help the member.
5. The bishop does not forgive sins. He can put a member under church discipline, if needed, to encourage repentance, and he can end the discipline. That is done by inspiration. But only God forgives sin. God can and does tell the Bishop what steps the person should be encouraged to take to facilitate repentance and forgiveness.
6. God expects church members to follow this process for serious sins, which helps lead to forgiveness and a stronger discipline to resist the same temptation the next time around.
7. Usually when a member talks to their bishop, they feel a great sense of relief and love. Bishops are compassionate and understanding.
8. While the bishop plays a necessary role in such cases of repentance, of course the individual prays for personal inspiration and draws closer to God through the process. There is no intermediary that stands between the individual and God. There must be a personal relationship between each of us and God. But we respect and understand the roles that God has appointed for his called and ordained ministers.
9. I have had around 30 LDS bishops in my life time and have known some better than others. I can honestly say that whenever I have needed a Bishop for any reason, my experience has been positive. I have always felt that they loved and cared about me and my situation. I have sensed at times that they received very specific and timely inspiration for me. A few of my bishops significantly helped shape the course of my life in a positive way.
10. Bishops are called from various walks of life. My current bishop is an attorney. Prior bishop is a retired telephone company man (climbed the telephone poles). One owned a business. One managed a Sears store. They work very, very hard in their callings. The have full time jobs and families and spend many hours a week as bishop. While they are not perfect and will at times offend someone or do something dumb, I have a lot of respect and gratitude for them.
