It is true that some part of the Bible are open to different interpretations but definitly not as far as the original sin and the salvation are concerned
I suppose that both fundamentalists and liberals agree on the following point

Jesus Christ died on the cross because of our sins

There is however a fundamental difference between Catholic and protestant conception of God, having a strong impact also in the society

Here in Italy we have been taught to think at God as a sort of Big brother alwayes willing to help us
This is not the God of the Bible, may be the God of the Gospel but not for sure of the Bible

The God of the Bible is justice He is not Love

Look around and observe people

Fair and honest people are very often mercy less people
Dont you agree ?

Apart from that I consider as an absurd the theory that God is not responsible for the earthquake

If He could prevent the earthquake from happening then He his responsible
If He could not then He is not God
