Paragraph 2. THE FATHER

From The Catechism of the Catholic Church

247
The affirmation
of the filioque does not appear in the Creed confessed in 381 at
Constantinople. But Pope St. Leo I, following an ancient Latin and Alexandrian
tradition, had already confessed it dogmatically in 447,⁷⁶ even before
Rome, in 451 at the Council of Chalcedon, came to recognize and receive the
Symbol of 381. the use of this formula in the Creed was gradually admitted into
the Latin liturgy (between the eighth and eleventh centuries). the introduction
of the filioque into the Niceno-Constantinopolitan Creed by the Latin liturgy
constitutes moreover, even today, a point of disagreement with the Orthodox
Churches.
