Doc Matthews gives a power-point lecture on the Arianism. This lecture corresponds with week 11 of his History of Christianity course.
*Note: I am not Doc Matthews, he is an instructor at the university I attend; I merely upload his video lectures for him on YouTube, as it takes too long for him to do it with his schedule and internet. All uploads of his lectures will now be handled by Doc Matthews himself rather than by me. You can find his videos and page at the following link: https://www.youtube.com/channel/UCURrLPaUGMthhz3UKfwTbbg/videos
