The minute you become a Calvinist you begin to spot heresy everywhere, because it is easy to find believers Doing Something, even yourself. This pernicious bug is so common it pops up not only in explicit thought but even in the way phrases are turned. The Christian side of the internet features many long, complicated arguments over whether such and such a person is a works person or not. It’s all quite nuanced. There are Christians who spend their lives at it. There are categories within categories.
I recommend, to wipe out heresy for all time, that all human action be expressed in writing by means of the passive voice.
