There have been many independent studies by non-christians into church history. The oldest church and the one that comes the closest, in today's society, to teach as it was taught from Jesus and the Bible is the "Orthodox Church". Everything they do and teach is based on the Bible and the teachings of Jesus Christ. "Traditions" are followed and explained. There are no secrets in this church and it is not ruled by a a few.
It is not easy to be an Orthodox Christian. The road is narrow but based on the Bible not human desires or human ideas.
As for the folks on tv who teach the word as they see it. Well I have listened and I have learned alot. But I was based in the Orthodox Church which gave the ability to sort through the televangelists teachings. I did drift from the church for a number of years and watched these broadcasts for several years. What I learned the most was to go back to the Orthodox Church.
As for the person who stated money was the root of all evil.... well I disagree. It is the "Love of money" not the money. I have been blessed several times with sums of money. I once sent in a prayer request for $90,000 so pay off all my bills (to one of the televangelists) and after a month or so I figured there was no way. Well about a year later I first received a check for $70,000 and 3 months later a check for $20,000. Several months ago I needed cash and here comes another check for $12,000. Last month I received another check for $30,000. Now with all that came alot of responsibility. For those whom I told it had to be known it was an answer to prayer. I had to give back to God what was his. I also have to have a ton of faith. I know God will provide for me and my family all my days. But He is my Father in Heaven and He does take care of his Children. I am still not debt free. That is my fault not Gods. I am still learning.
My biggest lesson: All things belong to God. I own nothing. It is all His. So.......... when the washer breaks I ask Him why he wants a broken washer. Makes me smile. Oh, by the way, I have a new washer. Thank you Jesus!
