Origen

“ For in Greek, Paraclete has both significations—that of intercessor and comforter. On account, then, of the phrase which follows, when he says, “And He is the propitiation for our sins,” the name Paraclete seems to be understood in the case of our Saviour as meaning intercessor; for He is said to intercede with the Father because of our sins. In the case of the Holy Spirit, the Paraclete must be understood in the sense of comforter, inasmuch as He bestows consolation upon the souls to whom He openly reveals the apprehension of spiritual knowledge. ”

“ It is time, then, that we say a few words to the best of our ability regarding the Holy Spirit, whom our Lord and Saviour in the Gospel according to John has named the Paraclete. For as it is the same God Himself, and the same Christ, so also is it the same Holy Spirit who was in the prophets and apostles, i.e., either in those who believed in God before the advent of Christ, or in those who by means of Christ have sought refuge in God. ”

“ For on some is bestowed by the Spirit the word of wisdom, on others the word of knowledge, on others faith; and so to each individual of those who are capable of receiving Him, is the Spirit Himself made to be that quality, or understood to be that which is needed by the individual who has deserved to participate. ”

“ And as there are many ways of apprehending Christ, who, although He is wisdom, does not act the part or possess the power of wisdom in all men, but only in those who give themselves to the study of wisdom in Him; and who, although called a physician, does not act as one towards all, but only towards those who understand their feeble and sickly condition, and flee to His compassion that they may obtain health ”
