In the gospel Jesus is not condemning the taking of oaths as much as he is condemning the way in which they very carefully parse the words. So somehow swearing by the gold of the temple is binding but swearing by the temple is not. In the old days Catholics would do the same with mass attendance. How much of mass must I attend for it to “count”?
In th post Vatican II days, it became how much stuff in mass can we change and how much made up stuff can we add on. The dodge used by this group was the untrue statement, “whatever isn’t forbidden is allowed.”
We are disgusted when we see our politicians and church leaders carefully parsing their words to explain how what they did want technically speaking illegal.
And yet, which of us does not on some level play this game. The speed limit is 60, but I am going 70, because no one is around. Even the phrase “white lie” is a dodge. What whitens a lie?
Jesus is once more calling us to. be better than this. Searching for excuses or clever rationalizations when we sin should not be the way we live. We should be honest, first of all, with ourselves.
And when we do sin, Jesus has given us the Sacrament of Penance through which we can be assured of forgiveness and receive the grace we need to be transformed.
