Read the history of the Crusades and notice how effectively the Mohammedans exploited the fault lines in Christianity.
well written and a shocking failure of us Christians as a whole. When we are disunited we fall.
We face two common enemies -- Islam and secularism/liberalism.
We must fight these together. Yes, we have a lot of serious disputes between ones -- some fundamental, others not so much, but we can be united on common issues and more importantly, we MUST be united on the common THREATS.
When we fight the war on Islam, the Catholics should not turn on the Calvinists, nor vice-versa.
After the war is over we can debate (key word "debate") and if we disagree, agree to disagree.
History teaches us that after Rome raises an army to fight an enemy she turns on those she considers heretics . Unity with Rome is a curse on Protestants . There would not be so many muslims if there was never created a vacuum for them to grow in the first place by killing all those you considered heretics.
