"over 33,000 distinct protestant denominations in 238 countries" ..and each of them is the 'correct' one?

People always distort what is true. There is one true church and you will know it by evaluating it along side of the standard that is the New Testament. It is simple and not difficult. Check out the book of Acts and your church. Any church that does more than what is exampled or less than what is exampled and commanded, then they are incorrect.
