Many other texts declare quite as clearly that the Holy Ghost is a Person, a Person distinct from the Father and the Son, and yet One God with Them. In several places St. Paul speaks of Him as if speaking of God. In Acts 28:25, he says to the Jews: "Well did the Holy Ghost speak to our fathers by Isaias the prophet"; now the prophecy contained in the next two verses is taken from Isaiah 6:9-10, where it is put in the mouth of the "King the Lord of hosts". In other places he uses the words God and Holy Ghost as plainly synonymous. Thus he writes (1 Corinthians 3:16): "Know you not, that you are the temple of God, and that the Spirit of God dwelleth in you?" and in 6:19: "Or know you not, that your members are the temple of the Holy Ghost, who is in you . . . ?" St. Peter asserts the same identity when he thus remonstrates with Ananias (Acts 5:3-4): "Why hath Satan tempted thy heart, that thou shouldst lie to the Holy Ghost . . . ? Thou hast not lied to men, but to God." The sacred writers attribute to the Holy Ghost all the works characteristic of Divine power. It is in His name, as in the name of the Father and of the Son, that baptism is to be given (Matthew 28:19). It is by His operation that the greatest of Divine mysteries, the Incarnation of the Word, is accomplished (Matthew 1:18, 20; Luke 1:35). It is also in His name and by His power that sins are forgiven and souls sanctified: "Receive ye the Holy Ghost. Whose sins you shall forgive, they are forgiven them" (John 20:22-23); "But you are washed, but you are sanctified, but you are justified in the name of our Lord Jesus Christ, and the Spirit of our God" (1 Corinthians 6:11); "The charity of God is poured forth in our hearts, by the Holy Ghost, who is given to us" (Romans 5:5). He is essentially the Spirit of truth (John 14:16-17; 15:26), Whose office it is to strengthen faith (Acts 6:5), to bestow wisdom (Acts 6:3), to give testimony of Christ, that is to say, to confirm His teaching inwardly (John 15:26), and to teach the Apostles the full meaning of it (John 14:26; 16:13). With these Apostles He will abide for ever (John 14:16). Having descended on them at Pentecost, He will guide them in their work (Acts 8:29), for He will inspire the new prophets (Acts 11:28; 13:9), as He inspired the Prophets of the Old Law (Acts 7:51). He is the source of graces and gifts (1 Corinthians 12:3-11); He, in particular, grants the gift of tongues (Acts 2:4; 10:44-47). And as he dwells in our bodies sanctifies them (1 Corinthians 3:16; 6:19), so will and them he raise them again, one day, from the dead (Romans 8:11). But he operates especially in the soul, giving it a new life (Romans 8:9 sq.), being the pledge that God has given us that we are his children (Romans 8:14-16; 2 Corinthians 1:22; 5:5; Galatians 4:6). He is the Spirit of God, and at the same time the Spirit of Christ (Romans 8:9); because He is in God, He knows the deepest mysteries of God (1 Corinthians 2:10-11), and He possesses all knowledge. St. Paul ends his Second Epistle to the Corinthians (13:13) with this formula of benediction, which might be called a blessing of the Trinity: "The grace of our Lord Jesus Christ, and the charity of God, and the communication of the Holy Ghost be with you all." — Cf. Tixeront, "Hist. des dogmes", Paris, 1905, I, 80, 89, 90, 100, 101.
As early as the first century, St. Clement of Rome gives us important teaching about the Holy Ghost. His "Epistle to the Corinthians" not only tells us that the Spirit inspired and guided the holy writers (8.1; 45.2); that He is the voice of Jesus Christ speaking to us in the Old Testament (22.1 sq.); but it contains further, two very explicit statements about the Trinity. In 46.6 (Funk, "Patres apostolici", 2nd ed., I,158), we read that "we have only one God, one Christ, one only Spirit of grace within us, one same vocation in Christ". In 58.2 (Funk, ibid., 172), the author makes this solemn affirmation; zo gar ho theos, kai zo ho kyrios Iesous Christos kai to pneuma to hagion, he te pistis kai he elpis ton eklekton, oti . . . which we may compare with the formula so frequently met with in the Old Testament: zo kyrios. From this it follows that, in Clement's view, kyrios was equally applicable to ho theos (the Father), ho kyrios Iesous Christos, and to pneuma to hagion; and that we have three witnesses of equal authority, whose Trinity, moreover, is the foundation of Christian faith and hope.
It is likewise an article of faith that the Holy Ghost does not proceed, like the Second Person of the Trinity, by way of generation. Not only is the Second Person alone called Son in the Scriptures, not only is He alone said to be begotten, but He is also called the only Son of God; the ancient symbol that bears the name of Saint Athanasius states expressly that "the Holy Ghost comes from the Father and from the Son not made, not created, not generated, but proceeding". As we are utterly incapable of otherwise fixing the meaning of the mysterious mode affecting this relation of origin, we apply to it the name spiration, the signification of which is principally negative and by way of contrast, in the sense that it affirms a Procession peculiar to the Holy Ghost and exclusive of filiation. But though we distinguish absolutely and essentially between generation and spiration, it is a very delicate and difficult task to say what the difference is. St. Thomas (I.27), following St. Augustine (On the Holy Trinity XV.27), finds the explanation and, as it the were, the epitome, of the doctrine in principle that, in God, the Son proceeds through the Intellect and the Holy Ghost through the Will. The Son is, in the language of Scripture, the image of the Invisible God, His Word, His uncreated wisdom. God contemplates Himself and knows Himself from all eternity, and, knowing Himself, He forms within Himself a substantial idea of Himself, and this substantial thought is His Word. Now every act of knowledge is accomplished by the production in the intellect of a representation of the object known; from this head, then the process offers a certain analogy with generation, which is the production by a living being of a being partaking of the same nature; and the analogy is only so much the more striking when there is question of this act of Divine knowledge, the eternal term of which is a substantial being, consubstantial within the knowing subject. As to the Holy Ghost, according to the common doctrine of theologians, He proceeds through the will. The Holy Spirit, as His name indicates, is Holy in virtue of His origin, His spiration; He comes therefore from a holy principle; now holiness resides in the will, as wisdom is in the intellect. That is also the reason why He is so often called par excellence, in the writings of the Fathers, Love and Charity. The Father and the Son love one another from all eternity, with a perfect ineffable love; the term of this infinite fruitful mutual love is Their Spirit Who is co-eternal and con-substantial with Them. Only, the Holy Ghost is not indebted to the manner of His Procession precisely for this perfect resemblance to His principle, in other words for His consubstantiality; for to will or love an object does not formally imply the production of its immanent image in the soul that loves, but rather a tendency, a movement of the will towards the thing loved, to be united to it and enjoy it. So, making every allowance for the feebleness of our intellects in knowing, and the unsuitability of our words for expressing the mysteries of the Divine life, if we can grasp how the word generation, freed from all the imperfections of the material order may be applied by analogy to the Procession of the Word, so we may see that the term can in no way befittingly applied to the Procession of the Holy Ghost.
In the first of these three passages we find nine charismata mentioned: the gift of speaking with wisdom, the gift of speaking with knowledge, faith, the grace of healing, the gift of miracles, the gift of prophecy, the gift of discerning spirits, the gift of tongues, the gift of interpreting speeches. To this list we must at least add, as being found in the other two passages indicated, the gift of government, the gift of helps, and perhaps what Paul calls distributio and misericordia. However, exegetes are not all agreed as to the number of the charismata, or the nature of each one of them; long ago, St. Chrysostom and St. Augustine had pointed out the obscurity of the question. Adhering to the most probable views on the subject, we may at once classify the charismata and explain the meaning of most of them as follows. They form four natural groups: 2b1af7f3a8
