Actually, that is not what they are saying. That is what you are interpreting. I encourage you to read CCC 845 and 846. Furthermore, I would encourage all Protestants here to read CCC 818. There have been references to Trent and Anathmas, and statements that anathmas can’t be revoked when dealing with a person. This is true, as evidenced by CCC 818. The Doctrines that Luther and Calvin, etc proposed are still held to be unorthodox by the Catholic Church, and the anathmas of those doctrines would still hold. However, individuals 500 years later can’t be held to the anathmas that Trent stated as the CCC “clearly points out”.

Here is a nice article from Catolic answers that explains Anathmas quite well.

I never said anything about anathma.
Edit to my own post, “This is not true, as evidenced by CCC 818”
