oaths & truthfulness, not truthy-ness

It's interesting to read how Bonhoeffer analyzes Jesus' words in Matthew 5:33-37. He argues that the reason that Jesus criticized the use of oaths is because of the existence of lies and lying - after all, if everyone told the truth all the time, there would be no need for anyone to swear an oath to "ensure" truth-telling. Instead, Jesus calls on us to be truthful ALL THE TIME - thus, we don't need oaths.

I like this quote:

"The commandment of complete truthfulness is really only another name for the totality of discipleship."
