Is it a sin to yell "Jesus Christ!" when I stub my toe? Or if I retweet an amazing footy try with the hashtag “OMG” for ‘oh my god’? What does it mean to 'take the Lord's name in vain'? I mean, which 'name', right? El? Elohim? Jehovah? Yahweh? Jesus? The "Lamb"? The "Rock of Ages"?

These, and more, I consider in this week's episode of Ask.
