The 3 secrets of fatima! (needs to be catholic) i need help understanding?

The delayed revelation of the final secret of Fatima left many of the faithful quite puzzled. Some think it has not yet been fully revealed. But you should not allow your faith to depend upon these apparitions. You are not even required to believe in them all. There is no sin involved by not believing in them. Our faith must not depend upon this at all. Try to take whatever good you find in them and apply it to your everyday life. Humans can sometimes distort the real truth in these apparitions.
