 The Catholic Church rejects the validity of Anglican Orders, defined formally in 1896 by Pope Leo XIII in the Papal Bull Apostolicae curae, which declares Anglican Orders "absolutely null and utterly void".Soon after the formulation of the branch theory, in 1864, the Holy Office rejected the branch theory or idea that "the three Christian communions, Catholic, Greek schismatic, and Anglican, however separated and divided from one another, nevertheless with equal right claim for themselves the name "Catholic" and "together now constitute the Catholic Church".In 1870, English bishops attending the First Vatican Council raised objections to the expression Sancta Romana Catholica Ecclesia ("Holy Roman Catholic Church") which appeared in the schema (the draft) of the First Ecumenical Council of the Vatican's Dogmatic Constitution on the Catholic Faith, "Dei Filius".
