It is with some amusement that I see a Catholic article on the Second Coming use as art background the "Second Coming" by a Seventh Day Adventist artist Harry Anderson .
Though this was I believe a Church of Latter Day Saint's commission . The fact that this well know artist took on Latter Day Saint's commissions is interesting as he was devout Seventh Day Adventist. This PDF is quite interesting into what and what he would not do for the Mormon Church. I always find his work wonderful too look at . My Grandmother was a Seventh Day Adventist so I key in on his artwork when it comes around a great bit.
Anyway good post by Monsignor Pope. When Will Christ Come? Some Basics of Catholic Eschatology
