What Ratzinger believes about salvation:

MAXINE MCKEW: Would Pope Benedict take the view that non-believers are damned? 

CARDINAL GEORGE PELL: No, certainly not, certainly not. Salvation is open to all good people. Our God is a god of love and infinite mercy. The only person who might be damned are those who resolutely refuse to turn to towards the light, towards love, who lock them up obstinately in hate. My prayer and my hope is that very, very few will be damned Read it here. 

What the Bible teaches:

If we receive the testimony of men, the testimony of God is greater; for the testimony of God is this, that He has testified concerning His Son. The one who believes in the Son of God has the testimony in himself; the one who does not believe God has made Him a liar, because he has not believed in the testimony that God has given concerning His Son. And the testimony is this, that God has given us eternal life, and this life is in His Son. He who has the Son has the life; he who does not have the Son of God does not have the life ( 1 John 5: 9-12 New American Standard Bible).
