69. The person who fulfills the promises he has made merits praise because he has sworn an oath before God and has remained faithful to it; conversely, the person who breaks his promises will be impugned and dishonored because he has sworn an oath before God and has been found false.
This text, of course, comes straight from the Sermon on the Mount. If we say we are going to do something, however we word it, then it counts as an oath before God. Our yes needs to be yes and our no, no. We like to make it more complicated and look for shades of gray that simply don’t exist.
