When I was searching through Christian forums, I came across alot of discussion about certain high profile preachers, teachers, prophets and their imperfections, and most were rejecting their teachings because of that. Just because you may have a problem with certain preacher's wealth, lifestyle, etc doesn't mean that you can ignore their teachings and be judgemental (James 4:12), unloving (John 14:24), and untithing (Malachi 3:8) etc.
Now I could debate the validity of some of these high profile Christian teachers and I can plead for your mercy or prove that they are right or wrong etc but that really isn't the point. No matter what happens or what God's chosen leaders may or may not do you still have the Word of God for yourself. God is perfect and He will never leave, forsake or lie to you. (Titus 1:2-3, Deuteronomy 31:6) So if you doubt a certain Pastor's teaching because of his or her lifestyle then you should learn the Word of God for yourself.
The Bible is the awe inspired living Word of God. If you think you can't understand it alone, pray before you read it and find guide books and a translation that can help you. It's also still good to attend church to help yourself clearly get a message from the Bible that you may have missed. But you can't rely on the pastor's perfection because there is no such thing. You can't rely on a perfect church because there's no such thing. We all need to approach Christianity as a relationship with God and to never forget that. You could attend the worst church in the world but if you have a strong relationship with God, He will still show you what you need to know and He still will help you grow. For an example you can turn on the TV and hear a passage preached in the Bible. If that Word is wrong God will lead you to the right meaning or the right meaning for you in your life as you spend time with Him in His Word.
John 1:1 "In the beginning was the Word, and the Word was with God, and the Word was God"
