So the two questions before us seem to be:
Actually I am being overly optimistic. Today the two sides rarely pose these two questions because to do so would assume that the issue is actually open for consideration. Those groups closed the discussion long ago and now unquestioningly declare their view as though it were fact.
I think a better approach would be to…
Most Americans would be unaware that Ramadan, the Muslim month of fasting, begins June 18 this year. Many would only be casually aware that this is one of the five pillars of Islam; the date changes each year due to the lunar calendar, but faithful adherents fast from dawn to dusk until the month concludes with the Feast of Eid.
Every language has its word for “God” which is used in translation of Scripture and within any particular culture and language. Allah is the Arabic word for the English “God” just as “Dios” is in Spanish. It is the word that has been used for centuries by Jews and Christians in the Middle East and actually pre-dates the founding of Islam in the seventh century. Bibles translated in predominantly Muslim countries into local languages such as Indonesian, Malay and Bengali use Allah as the biblical reference to the sovereign creator God.
To not use “Allah” for God would require the use of a foreign word that would not be understood in the local language. Ironically, the word “Allah” comes from the same root word of “Elohim” of the Old Testament, while our English word “God” has no etymological relationship to the biblical YHWH or Jehovah. In fact, it comes from the German “Gott” and was derived from the name of a pagan viking deity!
Use of Allah in Muslim literature refers to the God who created the world. He is the God of Abraham, Isaac and Jacob (and Ishmael), and other prophets known in the Old Testament. To introduce another identity than the monotheistic sovereign creator deity of the Bible and known as Allah by Muslims would create a formidable barrier to communicating biblical truth.
The concern is understandable that if “Allah” is used in Christian witness that the theological distortions of Muslim understanding will be carried over, resulting in syncretism or heretical concepts of God shaped by ones Islamic background. Certainly, this requires adequate teaching and discipling just as it does in our own culture. And we should be confident that when one comes in genuine repentance and faith to Jesus Christ that God is able to reveal Himself in spirit and truth to a new believer.
Is there more than one God? No, there is only one God, and He can be known only through Jesus Christ. We must not confuse cultural and linguistic bridges of communication in seeking to transcend diverse worldviews.
