Catholics know intellectually that the Catechism has changed -- many times.<quoted text>
I already told them about the catechism's are changed , they didn't believe me.
There really isn't much that hasn't been prove through scriptures ex catholic's and protestant, and out of the mouth of their own pope. To know that we are not liars.
Catholics simply can't accept that fact. Their belief system is exposed by 2000 years of irrefutable historical facts. Today, these facts are at our finger-tips, which causes Catholics here a great deal of anxiety.
"Tradition" is vital to their faith, yet all Catechisms and "perfect teachings" prior to Vatican 2 are conveniently forgotten.
Their tradition is like a lunch buffet of beliefs. Some is chosen to be consumed, and the rest goes into the trash.
Selective tradition = zero integrity.
