The article mentions Aid to the Church in Need ("a Catholic charity under the guidance of the Holy Father) http://www.churchinneed.org/
Barnabas Fund. Interdenominational Protestant ("Channelling money from Christians through Christians to Christians") https://barnabasfund.org/
I split my contributions among these three. Multiple channels of aid for a messy situation. No need to distinguish among Christian denominations -- the jihadis don't.
Great! God Bless you!
