Here we will focus on the most troubling part of this alliance, the entanglement of the Left-leaning 'Christian' churches around the world with the Islamic movement. This portion of the unofficial alliance involves churches on both sides of the Reformation divide. The Catholic Church has its portion within this alliance from the Pope on down the hierarchy of the church. Most of the Protestant churches involved are in cooperation with or are members of the World Council of Churches. In both cases, it is the Leftist application of the so-called "social justice gospel," that is employed to form and continue this unholy alliance.
