Satan is the enemy of God and His church. God's Catholic church is the unified fortress against all the powers of hell. They are many. All of the anti-catholic religions of the world combine with the atheists, the secularists and those of Freemasonry and Socialism. Moreover, the fake Catholics add to their number- the liberals, pro-aborts and those of the pro gay and LBGT disorders, along with the modernists, the radical trads and the promoters of the occult masquerading as Catholic Revelation- MDM, Garabandal, Medjugorje.
It's a war out there. Know the enemy.
