St. Anthony of Padua – 

Promise-keeping is the foundation of personal and social existence. If we cannot trust people to keep their word, then there is no basis for civil law, for business dealings, for personal friendships, or for family life. For that reason, we routinely expect people to swear that they are telling the truth. In today’s scripture reading Jesus is asking that we be supportive of one another not having to demand an oath over every aspect of life.
