telling people you know their heart better than God does, after falsely appraising their beliefs, is not getting you any closer to God.

For instance, incorrectly interpreting catholic beliefs as “your works save you alongside Christ” is not catholic teaching

Catholic teaching is based in scripture

be baptized in the name of the father son holy spirit

confess your sins one to another

eat of Christ’s body and drink of His blood

these are actions that you have to take to be saved

vatican 2 actually acknowledges that it may be possible to be saved without being baptized (for someone who has never heard the Holy Spirit and been compelled and rejected it)

So there are actions you must take to be saved according to Christ’s own words

Basically the idea is not that you earn your salvation

it’s that if a person is trying to self-assess and having a crisis of faith they may ant to take some specific actions to make sure they are right with God, to help strengthen their faith

such as prayer

devotion

charity

etc
