Hundreds of Hands Walking and Killing

There was a movie I saw in the 1990's on TV. A pair of hands (and I mean only hands) were in a hospital and began to capture people and cut off their hands.

Eventually there were hundreds of them just killing people and chopping off more hands and they would say, "join the messiah". In the end they all killed themselves by jumping off a building.

My question is, does anyone know the name of this movie?

Thanks in advance!
