I hope you're sitting down, we have a Christian missionary group setting up a debate 'Does Islam Teach Pure Monotheism?'
Now, even the one who has basic knowledge of Islam knows Islam teaches pure monotheism - all scholars of the faith will agree on this.
However, when you have a Christian apologist (Anthony Rogers) who actually believes an angel in the Old Testament is God one would not be so surprised such a debate is arranged as this Christian apologist's reckoning does not comply with orthodoxy, scholarship nor sound reasoning.
Here is a scholar to tell you what all other scholars of Islam will tell you - Islam is PURE MONOTHEISM:
"Our doctrine could not be more straight forward. The most pure, exalted, uncompromising monotheism: the clearest idea of God there has ever been" - Dr T J Winter
In fact, this 'debate' has already been executed in some capacity with Anthony Rogers' colleague (Sam Shamoun - who also, upon last check, shares similar views to Anthony Rogers). You can view the 'debate' here:
Having said that - this site may well feature a review for this debate as per Anthony Roger's previous debate: http://thefactsaboutislam.blogspot.co.uk/2013/07/debate-review-does-prophet-muhammad.html
Jesus taught people to do the Will of God (according to Mark 3:35) in order to become his brothers, mothers or sisters. A Muslim means one who submits to the Will of God. Do you want to become a brother of Jesus? If yes, become a Muslim. Now is the time.
