It's a series ("The Triune God and the Islamic God") of four articles by Imad N. Shehadeh, Jordan Evangelical Theological Seminary, Amman. I only have three as I get my Bibliotheca Sacras second hand. "Do Muslims and Christians Believe in the Same God?", v161, No. 641, Jan-March 2004, pp 14-26. "The Predicament of Islamic Monotheism", v161, No 641, April-June 2004, pp. 142-162. "Reasons for the Islamic Rejection of Biblical Christology", v161, No 643, July-Sept 2004, pp 274-288 "Additional Reasons for Islam's Rejection of Biblical Christianity", v161, No 644, Oct-Dec 2004, pp 398-412 The second article was of particular interest to me.
