Gifts of the Holy Spirit

Sicut ergo detestamur Arianos, qui inter Patrem et Filium aliquam volunt esse distantiam, ita etiam Macedonianos pariter detestamur, qui licet Patri et Filio tribuant aequalitatem, Spiritum tamen sanctum inferioris putant esse naturae: non considerantes eam blasphemiam se incidere, quae neque in praesenti saeculo, neque in futuro sit remittenda judicio, dicente Domino: Quicumque dixerit verbum contra Filium Hominis, remittetur ei; qui autem dixerit contra Spiritum sanctum, non remittetur ei neque in hoc saeculo, neque in futuro. Permanens itaque in hac impietate sine venia est, quia exclusit eum a se per quem poterat confiteri; nec umquam perveniet ad indulgentiae remedium, qui patrocinaturum sibi non habet advocatum. Ab ipso enim est invocatio Patris, ab ipso sunt lacrymae poenitentium, ab ipso sunt gemitus supplicantium; et nemo potest dicere Dominum Jesum, nisi in Spiritu sancto; cujus aequalem cum Patre et Filio omnipotentiam, unamque Deitatem evidentissime praedicat Apostolus, dicens: Divisiones quidem gratiarum sunt, idem autem Spiritus. Et divisiones ministrationum sunt, idem autem Dominus. Et divisiones operationum sunt, idem vero Deus, qui operatur omnia in omnibus. His, dilectissimi, aliisque documentis, quibus innumerabiliter divinorum eloquiorum conuscat auctoritas, ad venerationem Pentecostes unanimiter incitemur, exsultantes in honorem sancti Spiritus, per quem omnis Ecclesia catholica sanctificatur, omnis anima rationalis imbuitur; qui inspirator fidei, doctor scientiae, fons dilectionis, signaculum castitatis, et totius est causa virtutis. Gaudeant fidelium mentes, quod in toto mundo unus Deus, Pater, et Filius, et Spiritus sanctus, omnium linguarum confessione laudatur; quodque illa significatio, quae in specie ignis apparuit, et opere perseverat et munere. Ipse enim Spiritus veritatis facit domum gloriae suae luminis sui nitore fulgere, et in templo suo nec tenebrosum aliquid vult esse, nec tepidum. Sanctus Leo Magnus, Sermo LXXV

As therefore we detest the Arians, who wish there to be a difference between the Father and the Son, so also we detest the Macedonians, who, although they grant equality to the Father and the Son, yet think the Holy Spirit to be of a lower nature, not considering that they fall into that blasphemy which is not to be forgiven either in the present age or in the future judgment, for as the Lord says: 'Whoever shall have spoken a word against the Son of Man, it shall be forgiven him, but he who shall have spoken against the Holy Spirit, it shall not be forgiven him, not in this age, nor in the age to come.' 1 And so to persist in this impiety is unforgivable, because it severs a man from Him by Whom he could confess, nor will he ever have the remedy of pardon who has no Advocate to plead for him. For from Him is the invocation of the Father, from Him the tears of penitents, from Him the groans of suppliants, 'and no one can call Jesus the Lord save in the Holy Spirit,' 2 whose equal omnipotence with the Father and the Son and one Deity, the Apostle most clearly proclaims, saying, 'There are divisions of graces but the same Spirit. And the divisions of ministries but the same Lord. And there are divisions of operations but the same God, Who works all things in all.' 3 By these and other proofs, by which the authority of the Divine words are set ablaze, let us with one mind be incited to reverence of the Pentecost, exulting in honour of the Holy Spirit, through Whom the whole Catholic Church is sanctified, and every rational soul imbued, He who is Inspirer of the Faith, Teacher of Knowledge, Fount of Love, Seal of Chastity, and Cause of all Virtue. Let the minds of the faithful rejoice, that throughout the world One God, Father, Son, and Holy Spirit, is praised by the confession of all tongues, and that the sign which appeared in the likeness of fire persists in His work and gift. For the Spirit of Truth Himself makes the house of His glory shine with the brightness of His light, and in His temple He will have nothing dark nor lukewarm . Pope Leo the Great, Sermon 75 1 Mt 12:32 2 1 Cor 12:3-6 3 1 Cor 12:3-6
