How Do Our Beliefs Impact Our Memory?

As of late I have been wondering how the belief and value systems I have formed since age four have influenced my memory. I think our memory is one of our most remarkable faculties and yet science, research and theory still only suggest how it works. I really liked this quote...

"If any one faculty of our nature may be called more wonderful than the rest, I do think it is memory. There seems something more speakingly incomprehensible in the powers, the failures, the inequalities of memory, than in any other of our intelligences. The memory is sometimes so retentive, so serviceable, so obedient - at others, so bewildered and so weak - and at others again, so tyrannic, so beyond control! We are to be sure a miracle every way - but our powers of recollecting and forgetting, do seem particularly past finding out."
- Jane Austen, Mansfield Park, 1814 (1961)

Do your belief systems impact how you remember past events? Does how you remember past events impact your belief systems?
