He was an amazing man, but what is the most cool thing about him is his devotion to his Blessed Mother and his willingness to step up to sacrifice.
He started a magazine to spread the word about the devotion to the Immaculata (Immaculate Mother) and his Knights of the Immaculata; using the most modern mass communications of the era. If he was alive today I would betcha he would have a blog and website devoted to Her too! Sadly, he was was killed in Auschwitz, offering himself to die in the place of a young father.
Sacrifice in the most literal manner imaginable.
