It's not uncommon for Catholic teachings to be twisted into something they are not: A great example is that "Catholics Worship Mary" which is not a teaching of the Catholic Church. One of the things that I love about Catholicism is "The Catechism of the Catholic Church" because I can go direct to the true teachings of the Catholic Church rather than the false beliefs that exists like "Catholics Worship Mary." However, the Catechism is comprehensive with at lot of pages. That's why resources like the first link below can provide a general overview of what most Protestant Christians and anyone else seeking to know some key church teachings can find out ( * I have not cross referenced everything on the list and recommend that you verify teachings for yourself. ).

One of the many things that I love about the Catholic Church is the Catechism. Don't be mislead with bits and pieces used to misrepresent the Catechism without providing the full text in the Catechism, you should get your own copy. The Catholic Company is one of many places hat you can purchase the Catechism of the Catholic Church.
