Saturday of the Tenth Week in Ordinary Time
The devil is the father of lies and twists speech, including speech in court. In contrast when Elijah encounters Elisha he, under divine command, makes a prophetic gesture that is clear, while Elisha, after asking about the details, makes an ordination gesture that is equally clear. Jesus takes the teaching of the scribes inward. Not just a false oath is bad because it leaves us a debtor to God, but any oath, because they slip into casuistry (in the negative sense) and imply that there are levels of truth matching the levels of oaths. All such is of the devil, Rather we should be as straightforward and clear in speech as the topic allows. That will make us like God who is the truth and who deals with us in a straightforward way, even if his response is something “You will learn in due time.”
