A perpetual vow can be superseded by the Pope, when he decides that a man under perpetual vows should become a Bishop of the Church. In these cases, the ties to the order the new Bishop had, are dissolved as if the Bishop had never been a member; hence, such a person as Pope Francis, for example, has had no formal ties to his old order for years. However, if the Bishop was a member in good standing, he will be regarded, informally, as "one of us", and he will always be welcome in any of the order's houses.
