Yeah, I agree that centralized leadership with much of the power can be risky. If the one in charge is good and has pure intentions, a lot of good can be done. But all it takes is one corrupt leader with personal incentives to undo a lot of good and damage people's trust.
That being said, I am a firm believer in the organization of my church, the LDS church. Nobody in the church call aspire to positions of leadership, rather people who are already in higher positions of leadership choose ordinary members to fulfill certain callings and these members only fulfill that calling for a period of time. Nobody is paid for doing any of these callings. They give of their own time freely. This means greed is in no way motivation. I know that highest callings in the church that require a full dedication of time. meaning they cannot work to earn any money outside of their calling, will sometimes be supported so they can have their needs met. I do trust these men. I believe God can and does reveal who should fill these positions and guides them on the proceedings of the church. Every six months we listen to them speak in General Conference. I believe what they have to say is true. I don't ask any of you to trust them simply because I do, but if you want I would invite you to listen to what they have to say. I am not trying to impose anything on anybody but I see no point in withholding my beliefs simply because some people may disagree with them or even be angry with them. I simply want to put my beliefs out there so hopefully help others understand them more to allow them to form a more informed opinion to allow more informed decisions.
To be more on topic. I do believe there is God. Spiritual experiences are real. There just aren't explanations that are immediately obvious. Sorry for the disruptiveness of my post.
