Pope Francis said a martyr who refused to take the 'Hitler oath' after he was drafted into the German army in 1944 is a "model for fathers".

During his Angelus address on Sunday, the Pope discussed the beatification of Blessed Joseph Mayr-Nusser, which took place the day before in the Italian city of Bolsano, Vatican Radio reports.

After refusing to pledge his loyalty to Hitler, Blessed Joseph, who was a layman, father and promoter of Catholic Action, was sentenced to death. He later died on the way to Dachau concentration camp.
