A series for liars by liars

Do pastors ever teach about biblical contradictions? How about the PAGAN origins of Christmas and Easter? What about how the Gospels Matthew, Mark, Luke, and John were written decades after the events happened by UNKNOWN authors and that the names were pulled out of the air by early pastors and that we have no idea who really wrote them?

Or how about how no one believed "Jesus" was God until after the original apostles died?

No? Your pastor never mentioned this? He / she learned all of this in seminary school though
