I’ve been to speak with a priest plus briefly discussed this in confession as well. No help. And I’m planning on talking with my Lutheran pastor but pretty much know what he’s going to say. Both sides are biased.
I made the mistake of coming here looking for some help from non clergy. Guess I’ve learned my lesson.
So after a great experience at Mass I had a hunger to 'know' more. [Returning Catholic BTW]
So I sharpened iron against iron in General Theology until I was forced to search and find all of the history on the Church.
After several years of reading the Church fathers [and the background of Luther and most break offs in history], it became more evident to me that not only couldn't Luther ordain others, and left Apostolic succession, but he was angry at ethnic groups [Jews] and he attacked the Popes Chair but he himself made himself a pope of kind.
"We're gonna do it my way..."
His own friend said if you keep taking books out of canon, you won't have anything left.
He was angry at indulgences
which are in Maccabbees so he removed Maccabbees and then all the Koine Greek of the OT and then started going after St James. He pretty much 'created' his own ideas of what he felt scriptures were to mean.
He became paranoid. Even a lunatic at times. He became angry and boastful.
Martin Luther: hero, but no saint
1. He left the Church and could not understand why others who did the same just couldn't keep up with believing the Eucharist as the Body and Blood.
[well, if one makes a break from a history of one teaching and others follow - then it means all are free to pick and choose as it stands to reason.]
2. He decided indulgences were unnecessary, ignoring the festival of lights Hannukah and hating the Jews. [Maccabbees = Hannukah]
3. His hatred for his own father led him to rebel. He became his father.
4. He debated Calvin and Zwigli who also formed their own Churches. The more he became his own teacher, and not historical teaching, the more the protest against the ancient Church led to many new denominations growing and rising in numbers since.
5. He attacked the Papacy but demanded people follow his ways. Kind of ironic.
I don't describe him because I dislike him, I have read who is was a few times.
So all in all, in the end 'We know them by the fruits if from the Holy Spirit.'
Yet, the Lord never said to break away from His teachings.
Peter warned about such things.
The problem is you may need to research starting with the 1st century is the only way to figure out legit teaching.
FWIW -
Jesus travelled to celebrate the festival of lights [Hannukah] and had Jesus disagreed with giving silver to the Temple for the dead - I'm absolutely certain He would have said something.
