Decree XII

We believe the Catholic Church to be

taught by the Holy Spirit. For he is the true Paraclete; whom Christ sendeth from the Father, to teach the truth,t and to drive away darkness from the minds of the Faithful. The teaching of the Holy Spirit, however, doth not immediately, but through the holy Fathers and Leaders of the Catholic Church, illuminate the Church. For as all Scripture is, and is called, the word of the Holy Spirit ; not that it was spoken immediately by Him, but that it was spoken by Him through the Apostles and Prophets; so also the Church is taught indeed by the Life-giving Spirit, but through the medium of the holy Fathers and Doctors (whose rule is acknowledged to be the Holy and Cé£cumenical Synods; for we shall not cease to say this ten thousand times); and, therefore, not only are we persuaded, but do profess as true and undoubtedly certain, that it is impossible for the Catholic Church to err, or at all be deceived, or ever to choose falsehood instead of truth. For the All-holy Spirit continually operating through the holy Fathers and Leaders faithfully ministering, delivereth the Church from error of every kind. ο VO xy.,’26. Te Jonni xvi 13:
