"Muslim migration would fundamentally change our civilization."

Seems to me Christianity should be strong enough to withstand the clash of cultures with Islam. If these eastern bishops really do believe that adherents of Islam are so evil they should be shunned rather than welcomed, engaged, and ultimately, loved, as Christ taught us, have they forgotten the power of the Cross to overcome evil? Since that goes to the very heart of our faith, I find it more than a little disturbing that these bishops would have so little faith in the power of the Cross, but at the same time be so eager to close themselves and their flocks off from strangers in need of shelter, much like Mary and Joseph in Bethlehem. Maybe in the case of these bishops Christianity isn't strong enough to withstand the clash of cultures. But if they choose to close their hearts to the plight of these refugees and take up the sword against them instead they should also be prepared to die by the sword. And then meet God.
