Ultrajectine defines the tradition of the Old Catholic Church of the Netherlands headquartered at the city of Utrecht in the Netherlands. It is used to describe the anti-Papal-primacy and Jansenist tendency of that independent church and its sister churches, which were founded in later centuries (see Old Catholic Churches). Ultrajectine thought holds to the words of St. Vincent of Lerins: "We must hold fast to that faith which has been held everywhere, always, and by all the faithful." Ultrajectine thought rejects papal infallibility and holds to the belief that only the Church in Ecumenical Council may speak infallibly.
