Sanctification is a participation in the whole Trinity

For, in this way, he who is such as his Creator wished him to be, will receive from God power always to exist, and to abide for ever.  That this may be the case, and that those whom He has created may be unceasingly and inseparably present with Him, Who IS, it is the business of wisdom to instruct and train them, and to bring them to perfection by confirmation of His Holy Spirit and unceasing sanctification, by which alone are they capable of receiving God.  In this way, then, by the renewal of the ceaseless working of Father, Son, and Holy Spirit in us, in its various stages of progress, shall we be able at some future time perhaps, although with difficulty, to behold the holy and the blessed life, in which (as it is only after many struggles that we are able to reach it) we ought so to continue, that no satiety of that blessedness should ever seize us; but the more we perceive its blessedness, the more should be increased and intensified within us the longing for the same, while we ever more eagerly and freely receive and hold fast the Father, and the Son, and the Holy Spirit.  But if satiety should ever take hold of any one of those who stand on the highest and perfect summit of attainment, I do not think that such an one would suddenly be deposed from his position and fall away, but that he must decline gradually and little by little, so that it may sometimes happen that if a brief lapsus take place, and the individual quickly repent and return to himself, he may not utterly fall away, but may retrace

By the grace of the Holy Spirit and our free will we participate in Christ

Having made these declarations regarding the Unity of the Father, and of the Son, and of the Holy Spirit, let us return to the order in which we began the discussion.  God the Father bestows upon all, existence; and participation in Christ, in respect of His being the word of reason, renders them rational beings.  From which it follows that they are deserving either of praise or blame, because capable of virtue and vice.  On this account, therefore, is the grace of the Holy Ghost present, that those beings which are not holy in their essence may be rendered holy by participating in it.  Seeing, then, that firstly, they derive their existence from God the Father; secondly, their rational nature from the Word; thirdly, their holiness from the Holy Spirit,—those who have been previously sanctified by the Holy Spirit are again made capable of receiving Christ, in respect that He is the righteousness of God; and those who have earned advancement to this grade by the sanctification of the Holy Spirit, will nevertheless obtain the gift of wisdom according to the power and working of the Spirit of God.

Origen

Chapter III

The Holy Spirit is eternal with the Father and Son

We are not, however, to suppose that the Spirit derives His knowledge through revelation from the Son.  For if the Holy Spirit knows the Father through the Son’s revelation, He passes from a state of ignorance into one of knowledge; but it is alike impious and foolish to confess the Holy Spirit, and yet to ascribe to Him ignorance.  For even although something else existed before the Holy Spirit, it was not by progressive advancement that He came to be the Holy Spirit; as if any one should venture to say, that at the time when He was not yet the Holy Spirit He was ignorant of the Father, but that after He had received knowledge He was made the Holy Spirit.  For if this were the case, the Holy Spirit would never be reckoned in the Unity of the Trinity, i.e., along with the unchangeable Father and His Son, unless He had always been the Holy Spirit.  When we use, indeed, such terms as “always” or “was,” or any other designation of time, they are not to be taken absolutely, but with due allowance; for while the significations of these words relate to time, and those subjects of which we speak are spoken of by a stretch of language as existing in time, they nevertheless surpass in their real nature all conception of the finite understanding.

The Holy Spirit’s authority is equal to the the Father and Son

From all which we learn that the person of the Holy Spirit was of such authority and dignity, that saving baptism was not complete except by the authority of the most excellent Trinity of them all, i.e., by the naming of Father, Son, and Holy Spirit, and by joining to the unbegotten God the Father, and to His only-begotten Son, the name also of the Holy Spirit.  Who, then, is not amazed at the exceeding majesty of the Holy Spirit, when he hears that he who speaks a word against the Son of man may hope for forgiveness; but that he who is guilty of blasphemy against the Holy Spirit has not forgiveness, either in the present world or in that which is to come!

The Saints participate in the life of the Holy Spirit who is formless

And since many saints participate in the Holy Spirit, He cannot therefore be understood to be a body, which being divided into corporeal parts, is partaken of by each one of the saints; but He is manifestly a sanctifying power, in which all are said to have a share who have deserved to be sanctified by His grace.

The Lord is the Word and the Spirit of God

But if we turn to the Lord, where also is the word of God, and where the Holy Spirit reveals spiritual knowledge, then the veil is taken away, and with unveiled face we shall behold the glory of the Lord in the holy Scriptures.

Origen

Chapter I

The Scriptures are not clear to all

Then, finally, that the Scriptures were written by the Spirit of God, and have a meaning, not such only as is apparent at first sight, but also another, which escapes the notice of most.  For those (words) which are written are the forms of certain mysteries, and the images of divine things.  Respecting which there is one opinion throughout the whole Church, that the whole law is indeed spiritual; but that the spiritual meaning which the law conveys is not known to all, but to those only on whom the grace of the Holy Spirit is bestowed in the word of wisdom and knowledge.

Preface

The Son and the Spirit are also God

Jesus Christ Himself, who came (into the world), was born of the Father before all creatures; that, after He had been the servant of the Father in the creation of all things—“For by Him were all things made”—He in the last times, divesting Himself (of His glory), became a man, and was incarnate although God, and while made a man remained the God which He was; that He assumed a body like to our own, differing in this respect only, that it was born of a virgin and of the Holy Spirit:  that this Jesus Christ was truly born, and did truly suffer, and did not endure this death common (to man) in appearance only, but did truly die; that He did truly rise from the dead; and that after His resurrection He conversed with His disciples, and was taken up (into heaven).

Then, Thirdly, the apostles related that the Holy Spirit was associated in honour and dignity with the Father and the Son.  But in His case it is not clearly distinguished whether He is to be regarded as born or innate, or also as a Son of God or not:  for these are points which have to be inquired into out of sacred Scripture according to the best of our ability, and which demand careful investigation.  And that this Spirit inspired each one of the saints, whether prophets or apostles; and that there was not one Spirit in the men of the old dispensation, and another in those who were inspired at the advent of Christ, is most clearly taught throughout the Churches.

Let’s repay Christ with our patience

Let us, on the other hand, love the patience of God, the patience of Christ; let us repay to Him the patience which He has paid down for us! Let us offer to Him the patience of the spirit, the patience of the flesh, believing as we do in the resurrection of flesh and spirit.

The Logos brings a new kind of prayer

The Spirit of God, and the Word of God, and the Reason of God—Word of Reason, and Reason and Spirit of Word—Jesus Christ our Lord, namely, who is both the one and the other,—has determined for us, the disciples of the New Testament, a new form of prayer;
