Don't worry, the “doctor” is posting more falsehoods.
There is an on-line version of the book by Anthony Read which the “doctor” cites. The “doctor” claims that the book relates that Herr Himmler was a “life-long Catholic.”
This doesn't appear to be true.
In browsing through the on-line preview version of The Devils Disciples: Hitler's Inner Circle available via Google book search, I found this on page 120:
[This is after the failed putsch in 1924 - not exactly the end of Herr Himmler's life]
“Himmler's world collapsed around him. He had no job and little chance of finding one. Along with the Nazi Party, the SA, and the entire Kampfbund, Kompanie Werner, on which he had pinned his last hopes of a military career, had also dissolved. At the same time, his Catholic faith was fading fast - by summer, he would have broken with the church forever, replacing the mysteries of the mass with the secrets and the subterfuge of the revolutionary underground, into which he plunged with equally religious fervour.”[emphasis added]
So much for Mr. Read's book telling us that Herr Himmler was a life-long Catholic. In fact, the source so fervently cited by the "doctor" turns out to tell us that Himmler basically wasn't a Catholic for the LAST 20 YEARS OF HIS LIFE. LOL.
As Google provides only a limited preview mode, I was unable to check on the other likely false assertions of the “doctor.”

Himmler was never excommunicated. Himmler never renounced his Roman Catholicism.
