Ecumenical XIV (concerning the union of the Greeks)

460 In faithful and devout profession we declare that the Holy Spirit proceeds eternally from the Father and the Son, not as from two beginnings, but from one beginning, not from two breathings but from one breathing. The most holy Roman Church, the mother and teacher of all the faithful, has up to this time professed, preached, and taught this; this she firmly holds, preaches, declares, and teaches; the unchangeable and true opinion of the orthodox Fathers and Doctors, Latin as well as Greek, holds this. But because some through ignorance of the irresistible aforesaid truth have slipped into various errors, we in our desire to close the way to errors of this kind, with the approval of the sacred Council, condemn and reject (those) who presume to deny that the Holy Spirit proceeds eternally from the Father and the Son; as well as (those) who with rash boldness presume to declare that the Holy Spirit proceeds from the Father and the Son as from two beginnings, and not as from one.
