Let’s start with this premise: Do Muslims consider Jesus to be “true God”? That’s how Wheaton’s statement of faith puts it.
You seem to want to argue points about “Muslim-Christian relations” and whether Muslims share the the same Godhead.
You also seem to advance think that some Muslims in Ethiopa advancing “Jesus as the Messiah” or “Jesus as the Word” has something to do with this.
You are incorrect.
What is at issue here is Wheaton’s statement of faith; not a general history of Christianity nor what other groups have thought through the years.
Wheaton’s statement of faith is clear: God is a triune God, and Jesus is true God as part of the Trinity.
Muslim teaching is equally clear: Jesus is a prophet, but not true God. In Islam there is only one true God, and the Trinity is blasphemy.
*“In Christianity, the doctrine of the Trinity states that God is a single being who exists, simultaneously and eternally, as a communion of three distinct persons, the Father, the Son, and the Holy Spirit. Within Islam, however, such a concept of plurality within God is a denial of monotheism and foreign to the revelation found in Muslim scripture. Shirk, the act of ascribing partners to God – whether they be sons, daughters, or other partners – is considered to be blasphemous in Islam.”

It is completely irrelevant what someone said somewhere about Christianity, since Wheaton’s statement of faith is very specific and Wheaton’s hiring policy requires faculty to sign that exact verbiage.
As to whether or not Islam thinks Jesus is true God, I think you’ll need more than some fleeing Meccans to suggest that the average Islamic position is that Jesus is true God.
You can see my comments earlier about why the Jewish and Christian Yahweh is similar to the Islamic Allah. I mean, when you are making up stuff you can define anything as anything, and steal the other guy’s God as you please.
But Wheaton is stuck on differentiating those who accept the deity of Jesus from those who do not, and it is this point that for them makes it unacceptable–particularly for a faculty member who signed the statement of faith–to proclaim that Muslims and Christians worship the same God.
It is not the case that the average Muslim consider Jesus to be true God, but it is the case that Wheaton’s statement of faith requires accepting that as a condition to be faculty.
