I can’t help you with who you know and what name you give them. Christians believe and obey the entire word; otherwise they aren’t Christians.
Catholics have their own man made teachings and are the ones who pick and choose to fit their man made teachings. Catholics do not understand God’s Word because it is spiritually discerned. They are a worldly group.
You have your own man-made doctrines. One is sola scriptura.
I don’t see much real value in such a designation as you seem to be promoting. There are many Christians in the world who fall from perfection in accepting everything they should, or following through on living that out, and yet they are still Christians. Language just doesn’t work the way you wish it did. Christians come in many forms, from the nearly perfect to the very flawed, and there is no indication that they stop being Christian because of their failure. Bad Christians may be, but Christian still.
