:::: I agree with what he says only the part aboout the fallen angels, angels do not go against the will of the creator, I believe unseen evil spirits and evil humans have altered this part, evil unseen spirits are devils, spirits are made of fire in the context that we humans are made of clay. angels of light. and so on ,,, these so called ''fallen angels'' are spirits,  fallen accursed spirits (not angels); unseen evil spirits often lie to humans that they are angels while they are spirits.

note:"devil" is a name/title given to those who go against the will of the creator which is goodness. A devil practices the opposite of goodness which is evil so which means a spirit and a human can be called a devil.
