Costume of Prelates of the Catholic Church was first published by in 1909 by Fr. John Abel Nainfa. This necessary work details the correct usage of vestments and other ecclesiastical dress for clerics. Included are details about the history, specifics, and restrictions placed on each clothing item for various ranks of clergy. St. Gabriel Theological Press decided to republish the work for the use of the Old Roman Catholic Church in America, as well as to benefit a wider audience of traditionalists.
