In what sitcom did John Ritter play a minister?

"The Waltons"

But he is best known in "Three's Company"

I didnt know he was in any Waltons episodes..... That would be nice seeing!

If he was a minister than I reckon he is in alot of episodes...........

Yes, John Ritter was in 18 episodes of The Waltons portraying Reverend Fordwick between the years of 1972-1976.

Wow 18,God bless him!!
