15. They Are Actually A Non-Religious Sect... So Claims They Carry Out Christian Deeds Are False
In popular culture - including in the film and book "Angels and Demons" - the Illuminati are often portrayed as a religious order, sometimes even with links to the papacy and the Catholic Church.
However, the Illuminati was actually set up as a secular, non-religious sect who wanted to dismiss religious influence over public life and state power.
Unlikely that the Pope is going to be a member, don't you think?
