That depends on who you talk to. The “Judas Replacement Theory” is a popular one nowadays, but others think Jesus merely passed out on the cross, some think God made his suffering and death and illusion to those watching, some think the passion, crucifixion and resurrection is a lie and it all never happened, others say it’s just a mystery and we shouldn’t worry about it, and countless other examples.
The website treats Christ in a fashion typical of many Muslim apologetic sources,
especially as is seen on this page. Especially telling is this section:
That first group of passages, when looked in context, do not teach that Jesus says we should worship God and not him. The second group of verses do call Jesus the “servant” of God, but what we have here is the usual problem of presupposing unitarianism rather than trinitarianism. Most of these verses, which Muslims will throw at Christians as if they destroy the idea of Christ’s divinity, are perfectly fine within the context of Trinitarian Persons (ie., the Son interacting with the Father, the role of the Son and the Father within the Divine Godhead, etc.).
One of the most saddening things to me regarding Islamic apologetics against Christianity is that it never evolves. It has stayed the same for the past ten years or so, maybe more. The same arguments that have been responded to
ad nauseum are thrown about as if they’re brand new. I really pray that God uses these dishonest tactics and shallow answers to wake many up and make them seek the truth in the real Christ, a Christ who is not merely a prophet but is a King who saves his people.
