“Chrislam” would be apostasy to Moslems and good for a death sentence.
And, for Christians, if there is no savior, there is no point.
But Chrislam does make sense with one condition. We discussed the "rapture" in our (coonservative) Bible class for several weeks. After all the believers are gone, the ones left are subject to a great deception. Chrislam, or a variation of it, must be part of this deception. A one world religion.
