Sola Fide - Luther, when understood properly
Sola Scriptura - Luther, when understood properly, not the oft mentioned “evangelical” approach, more correctly called
solo scriptura. As a result, we use the creeds, have a confessional document, and accept at least the first six councils.
**
Predestination - Not Luther
**
Assurance of Salvation** - Not Luther
Total Depravity - Not sure where it came from first, but I know it is the “T” in Calvinism’s TULIP
The Catholic church is Apostate - for me to deny that Luther thought there were errors in at least Catholic practice of his time would be silly. I don’t know if Luther ever used the word apostate in this sense.
Any believer can correctly interpret Scripture - not Luther in the current understanding
**Ordained ministers (anyone can be ordained if they believe they are called) ** - not Luther
The church is a visible human institution (but not a unified institution) - I’ve never heard this, so I don’t know
The supreme importance of preaching - Not Luther. The preaching of the word is but one of the means of grace, as are the sacraments. The Sacrament of the Altar is the center of Lutheran worship, according to the confessions.
No, the core of all Christian teaching is, at least for Lutherans, well stated in the Creeds, and as you correctly state, the early councils. Your understanding of Luther is a bit muddled, which is understandable if you weren’t raised Lutheran (even some of us, too

), and haven’t studied him. As I have been recommended to read the CCC to understand Catholicism, I recommend you read the Lutheran Confessions.
