Which lord? 
I don't know enough about it, I could be wrong, but I'm about 80% sure that Hitler never really professed to be a Christian.
Yes... Yes he did.
Just a quick google search to get the information correct.
a) Hitler was baptized as Roman Catholic during infancy in Austria.
b) As Hitler approached boyhood he attended a monastery school. (On his way to school young Adolf daily observed a stone arch which was carved with the monastery’s coat of arms bearing a swastika.)
c) Hitler was a communicant and an altar boy in the Catholic Church.
d) As a young man he was confirmed as a “soldier of Christ.” His most ardent goal at the time was to become a priest. Hitler writes of his love for the church and clergy: “I had excellent opportunity to intoxicate myself with the solemn splendor of the brilliant church festivals. As was only natural, the abbot seemed to me, as the village priest had once seemed to my father, the highest and most desirable ideal.” -Adolf Hitler (Mein Kampf)
My feelings as a Christian points me to my Lord and Savior as a fighter. It points me to the man who once in loneliness, surrounded by a few followers, recognized these Jews for what they were and summoned men to fight against them and who, God’s truth! was greatest not as a sufferer but as a fighter. 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 to drive out of the Temple the brood of vipers and adders. How terrific was His fight for the world against the Jewish poison. To-day, after two thousand years, with deepest emotion I recognize more profoundly than ever before the fact that it was for this that He had to shed His blood upon the Cross. As a Christian I have no duty to allow my self to be cheated, but I have the duty to be a fighter for truth and justice… And if there is anything which could demonstrate that we are acting rightly it is the distress that daily grows . For as a Christian I have also a duty to my own people." –Adolf Hitler, in a speech on 12 April 1922
We were convinced that the people needs and requires this faith. We have therefore undertaken the fight against the atheistic movement, and that not merely with a few theoretical declarations: we have stamped it out.” -Adolf Hitler, in a speech in Berlin on 24 Oct. 1933 [This statement clearly refutes modern Christians who claim Hitler as favoring atheism. Hitler wanted to form a society in which ALL people worshipped Jesus and considered any questioning of such to be heresy. The Holocaust was like a modern inquisition, killing all who did not accept Jesus. Though more Jews were killed then any other it should be noted that MANY ARYAN pagans and atheists were murdered for their non-belief in Christ.
