This letter attempts to find common ground where, in fact, none can exist except that of a Christian serving his or her neighbor, and evangelizing them. Unfortunately the letter goes beyond that, and asserts common purpose between Christians and Muslims. This is a sewrious error, and I would hope that the home churches of these signees would hold them accountable.
Exactly. There is very little “common ground” to be found between true Christians and Muslims. I suppose we both oppose abortion and pornography, but there’s a whole world of other issues on which we are completely at opposite ends. Spiritually there is no common ground at all.
