'Snake Salvation' Church -- Deadly Rattler Back in Church for Round 2

The rattlesnake that killed "Snake Salvation" Pastor Jamie Coots a week ago made an encore appearance Saturday night at the same church with Jamie's son at the helm ... and this time no animals or people were hurt.

Cody Coots prayed over a bevy of snakes -- one of which was the rattler that killed Jamie. The video is insane ... it looks like a revival service with a live band and snakes and worshipers all flailing in the air.

As we told you ... Cody made it clear to us ... if the rattler bit him he would refuse treatment ... just like his dad.

But snakes weren't the only trick up Cody's sleeve. He also played with fire ... literally.
