CLP or CVP Yamaha Clavinova for a Church Setting?

With the short supply of available organists our church wants to purchase a clavinova so that in the absense of an organist, maybe even a piano player, the non musician can "play" a prerecorded church service. Which series would be best for this purpose? Would it be the CLP or CVP? We don't want to have a series of items hooked up in order to do this. We want the clavinova itself (with a memory card? or????) to have the capability to play a prerecorded service with just the press of a button.
