Islam is really a Christian heresy
President Obama should not be issuing apologies for the military's burning of the Koran. He should be seeking apologies from Muslims for their persecution of Christians in the Middle East.
In his book The Great Christian Heresies, Hilaire Belloc classifies Islam as a Christian heresy. The foundation of Mohammed's teaching is Catholicism, which he took and simplified to suit his own personal convictions.
His central teaching is a full denial of the Incarnation. He taught that our Lord was merely a prophet; a man like other men.
