German dictator and Nazi leader Adolf Hitler professed to be a Christian during his lifetime, and claimed to have done acts in the name of God. However, Christian author Matt Barber believes otherwise.

"Yes, there have been evil men who have done evil things in the name of false Christianity. To a limited degree, Adolf Hitler was one such man. Still, and as even he frequently admitted outside the public eye, he was no Christian," the former undefeated heavyweight professional boxer turned lawyer writes in an article for Charisma News.

Under Hitler's authoritarian rule, German soldiers carried out the mass slaughter of over 11 million Jews, Christians, disabled people, and other "undesirables," historical records show.

Barber says Hitler was a "plastic" Christian who only used the faith to disseminate political propaganda and justify the deaths of the Jewish people.

"My feelings as a Christian point me to my Lord and Saviour as a fighter," Hitler claimed in his book "Mein Kampf."

"In boundless love as a Christian and as a man I read through the passage which tells us how the Lord at last rose in His might and seized the scourge [the Jews] to drive out of the Temple the brood of vipers and adders. How terrific was His fight for the world against the Jewish poison. For as a Christian I have also a duty to my own people," Hitler wrote.

Barber says Hitler was also an apologist for Islam since he linked up with Iran and other Islamist regimes in an effort to wipe out Jews from the face of the earth.

"Hitler also parroted the godless ideology of modern atheists. Like so many of today's secular progressives, he was an avowed materialist, neo-Darwinian evolutionist and hardhearted God-denier," says Barber.

The author says there was no way Hitler could be a Christian because he encouraged the youth of Germany to be "absolutely indifferent in the matters of religion."
