I remember a few years ago the maried couple that he step forward to spare their life was still with us. I don't if they are still living.
Talk about strength his captures tried starving him to death I think 3times and he lived, finally had to give him a lethal injection af battery acid.
I hear the man giving that injection had a very hard time as Kolbe looked him in the eyes and he could not handle what he saw in Kolbes eyes yelling at him to turn away, this is from my memory of reading about his life so my facts may not be accurate. (Holy disclaimer, lol)
I'm glad to hear your son is a Knight of the Militia Immaculata. I too, am a Knight (do they call women knights??). My anniversary is October 7, the date I was installed.
St. Maximilian Kolbe has been a great influence in my life and his unselfish love for Our Lady combined with his heroism in giving up his life for another has always stuck with me. "Greater love hath no man, who lays down his life for his friends."
God Bless your Son, Oceanperch!
