Is Protestantism dead? Isn't each person supposed to interpret Scripture for himself - with the aid of H.S.?

>>Isn't each person supposed to interpret Scripture for himself - with the aid of H.S.?<<

We can see how well that has worked out...countless Protestant denominations, sects, cults, etc...

The Christian church is very diverse. I have worshipped in many different denominations. I think the reason that there are many different denominations is that there are many different personallities in people. For many they feel more comfortable in a certain church.

One thing that I have noticed is that most song the same songs. This is a real uniting force.

Then if all the interpretations do not agree, who's is correct?
