Heraldry in the Catholic Church

Heraldry in the Catholic Church has a long history dating back the 13th century. Heraldry - the science and art of coats of arms - originates in the European warfare of the early middle ages when men went into battle covered with armor and enclosed helmets. Kings, nobles, and knights needed a way for their soldiers to recognize them when fully covered in armor, and so they began using unique designs on their shields to distinguish them. This practice was so successful that these designs and symbols then began to be used on all sorts of objects - wax seals, banners, tunics, etc - and subsequently the practice spread to all ranks in society, not just the nobility and soldiers. It was in this way that heraldry entered the Catholic Church, at first being primarily used in seals. Though such symbols and designs would never be used on actual shields in battle, dioceses, cathedrals, churches, abbeys, religious orders, and clergy all displayed arms. This tradition of heraldry in the Church is still strong today.

Ecclesiastical arms can be divided up into two categories: personal arms and corporate arms. Personal arms are those that belong to persons, such as clergy or religious. Corporate arms are those that belong to organizations, such as dioceses, schools, and religious orders. Personal arms enjoy widespread usage across much of the globe, being employed by most of the world's Catholic bishops. Though much less common, lower clergy and religious also use personal arms. Corporate arms, on the other hand, are largely limited to the English speaking world and Western Europe, although there has been a recent increase in their use in South America.

Personal heraldry in the Latin Rite of the Catholic Church is regulated by almost seven centuries of tradition and various papal instructions. The first attempt to standardize ecclesiastical heraldry into a coherent system was in the early 1600s by Pierre Palliot, and in 1644, Pope Innocent X's bull Militantes Ecclesiae prohibited cardinals from displaying as ornaments on coats of arms any secular privileges, such as symbols of knighthood, nobility, or anything else not proper to the clerical state. (This prohibition was extended in 1915 by Pope Benedict XV to all bishops and patriarchs.) The elaborate and coherent structure we see today, however, was only implement in 1905 by the Pope St. Pius X in Inter Multiplices Curas. This system was further modified by Pope Paul VI's instruction Ut Sive in 1969. An explanation of this complete system along with relevant papal documents can be accessed through the Catholic Heraldic Norms link below.
