I have known many cafeteria Christians. People have long thought you could pick and choose what tenets or doctrines to support and ignore the rest. Hardly something limited to Catholics.
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.
