While this might seem pedantic, technically orders are not created all the time. People think there are thousands of Franciscan orders, but they are generally third order Franciscan communities that go by various names. They all are part of the (single) third order of St Francis. Others are not orders at all, but societies of apostolic life. For instance the Priestly Fraternity of St Peter (FSSP) is not a religious order, but rather a clerical society of apostolic life of pontifical right. The Vincentian’s, Sisters of Charity and hundreds others also are not technically religious orders, but congregations.
Like I said, it’s pedantic, but there are differences between a religious priest like a Jesuit and a Vincentian priest (i.e. one takes public vows and the other doesn’t). How that all plays out under the 1983 canon law is not as clear as it was before the 20th century.
