In 1710 it became a decreed "dogma"
that a STUFFED DONKEY at
the church of the Madonna of the Organs in Verona, Italy, is the actual animal Yahusha rode into Yerushalayim on.
When I first heard about this, I couldn't stop laughing for about 10 minutes. Many other dogmas like this are included in the Roman Catholic Church Timeline (click link) and in the book Fossilized Customs.
