Help with identifying a TV show

A while back I saw half of great episode but I don't know what of. The story was that angels came to earth, falling in coffin type containers, and then various humans started chanting messages that were it seems from God. The message was that we had blown it and god was about to wipe us out. Anyone know the series so i can watch other episodes. Thanks.
Thaaks for the suggestion but G vs E was a serial and this was a one off in a series. I assumed it was 'the outer limits' - the newish one - but can't find it listed.
