For those who cherry pick Scripture to support bringing in all of the refugees.

I can do that too!  I've got two parts to comment on here.

2 John 1:7-11(NKJV)

For many deceivers have gone out into the world who do not confess Jesus Christ as coming in the flesh. This is a deceiver and an antichrist. 

Look to yourselves, that we do not lose those things we worked for, but that we may receive a full reward.

Whoever transgresses and does not abide in the doctrine of Christ does not have God. He who abides in the doctrine of Christ has both the Father and the Son. 

If anyone comes to you and does not bring this doctrine, do not receive him into your house nor greet him; 

for he who greets him shares in his evil deeds.

The first part again points out the need to believe that Jesus came in the flesh.  The big problem here is that we are starting to see some of the big, more Liberal churches actually starting to question and in some case reject that belief. 

Heck at an Episcopal Church Synod about a decade ago they couldn't even get support for a motion from the floor to reaffirm that the Bible is the inspired word of God!

Now to my second point.  It is always funny to me to see people who are normally hostile to religion suddenly try to use Scripture to support one of their own points.  As I have said many times the Bible is a book of balance and needs to be interpreted in its entirety. 

But I can play the cherry picking game like anybody else if I want to so let's take a look at the second highlighted part above.

This passage was written by the Apostle John.  John flat out says that if they don't believe the doctrine of Christ then not only shouldn't we let them in to our house (or country as the case may be), we shouldn't even greet them.  Now there is no doubt that Muslims do not abide in the Doctrine of Christ.  If they did they would be Christians, not Muslims.  :)  Therefore this Scripture is talking about them as well as others.

Now do I really think that this is the ultimate Scripture on the subject?  Nope.  As I said before you have to take the whole Bible in context.  But I do think that this Scripture is strong enough to refute the charge that in all cases it is "unChristian" to exclude the refugees.  We have a Scripture here that tells us that in some cases at least, it is the "Christian" thing to do.
