“Developing from Girolama Zanchi’s exegetical labors through Ephesians, Spiritual Marriage draws readers into the rich theological of doctrine of union with Christ.  Following the lead of the apostle Paul, Zanchi demonstrates how our earthly marriages fulfill their truest purpose by drawing our attention toward the spiritual marriage between Christ and His Church.  By paying attention to the Genesis account of Adam’s marriage to Eve, to pertinent Old Testament laws, and to the teachings of Jesus and His apostles, we begin to understand something of that higher and heavenly union.”

Ferguson (c. 1637–1714) was a Scottish, presbyterian minister.

Sherlock was a rationalizing, Anglican bishop and influential writer.  Ferguson quotes him as saying, “…the methods of divine grace are denyed to consist in the producti∣on of any new principles by an omnipotent & irresistible Power…” (p. 430), that is, he denied monergistic regeneration and any vital, organic, spiritual union of Christ with believers, thus allowing natural men to adopt Christianity as natural men.

After introductory discoursing, sections 6-12 deny, one by one, the believer’s union with Christ to be the same as other unions: 6. the hypostatic union, 7. a bodily union, 8. a union of becoming the same person, 9. not only a legal union, 10. not merely a union of love, 11. not by a previous union to the Church, 12. not a political union.  Section 13 is: “An Intelligible Notion of it assigned, and the whole shut up.” (pp. 653-65)

pp. 656-661:

“1st. The highest and closest union is between those things that are actuated by one spirit dwelling and moving in them…

2dly. Things at the greatest distance, and between which there is no physical continuity, may be acted by the same spirit, providing he be immense and infinite…

7ly. Through the communication of the Spirit from Christ to us, and immediately upon his taking the possession of us, the nature of Christ, the seed of God, and a vital living principle comes to be formed in us.”

Jerome Zanchi

pp. 71-72  of ch. 11, section 15  in H. Zanchius his Confession of Christian Religion…  (Cambridge, 1599)

“…and that in our name He took unto Himself possession of the heavenly inheritance: ‘and sits at the right hand of God’ (Eph. 1:20), that is, has taken to Himself power over all things in heaven and in earth: So that, in asmuch as He is our Mediator and is man, He has obtained of his Father the second place: is appointed head of the Church, as well which is in heaven, as which is on earth: that from Him, and even from his flesh, is conveyed by his Holy Spirit, whatsoever pertains to the quickening and to the spiritual life of us, to all those, which as members are fastened unto Him their head.

And therefore we acknowledge, believe and confess that in Christ alone is placed our whole salvation, redemption, justice, favor of God and eternal life: according to that saying, ‘Who of God is made unto us wisdom and righteousness, and sanctification and redemption’ (1 Cor. 1:30): Also, ‘He is our peace’: Also, ‘Jehouah our righteousness’, ‘in Him we have redemption by his blood, forgiveness of sins’:  Also, ‘It pleased the Father that in Him all fullness should dwell’: Also, ‘Life is in his Son’ (Eph. 2:14; Jer. 23:6; Eph. 1:7; Col. 1:19; 1 Jn. 5:11).

And therefore we know that the promise concerning redemption, which was made unto the first man, did receive accomplishment in this other man Jesus Christ: so that whosoever will be made partaker of it, he must needs be joined to his head Christ and be made a member of Him.  For we have redemption and salvation not only by Him, as a Mediator, but also in Him, as our head.  This is our faith concerning Christ the redeemer, his person, natures, and office, and the salvation of mankind fulfilled and laid up in Him.”

“XI.  Therefore all Christ is everywhere, although
his human nature, since his ascension untill the
day of the Last Judgment, be nowhere but in Heaven.

Mt. 28:6, ‘He is risen, he is not here,’ Mt. 26:11, ‘Me ye have not always with you.’ Jn. 16:28;  ‘I leave the world and go unto my Father.’  Acts 3:21, ‘Whom the heavens must contain, until the time of restoring of all things.

XII.  And the godly in what place of heaven or
earth so ever they abide, are united to the human
nature assumed by the Son of God, as members to
their head, the same Holy Spirit dwelling in Christ
by unity of essence with the Word, and in the godly
by grace.

in us, because He hath given us of his Spirit.’  Rom. 8:11,

‘unio essentialis’

essential union; i.e., a union of two different essences, such as the union of all things with God according to the divine omnipraesentia (q.v.) and omnipotentia (q.v.) and manifest in the divine concursus.

This union of God with all things can also be called the unio generalis, or general union, inasmuch as it belongs to the universal nonsaving work of God as opposed to the unio specialis or unio mystica (q.v.).”



In What Way Union to Christ is Before & After Faith


Flavel, John – Sermon 6, ‘That the Receiving of the Lord Jesus Christ is that Saving & Vital Act of Faith which gives the Soul Right both to his Person & Benefits’  in The Method of Grace, in bringing Home the Eternal Redemption…  wherein the Great Mystery of our Union & Communion with Christ is Opened & Applied…  (d. 1708; London, 1681), pp. 113-34

Witsius, Herman – Ch. 6, ‘Whether the Elect are United to Christ Before Faith…’, Sections 1-4  of Conciliatory or Irenical Animadversions on the Controversies Agitated in Britain: under the Unhappy names of Antinomians & Neonomians  (Glasgow, 1807), pp. 67-9

In sections 1-2 Witsius carefully defines the union of Christ to the elect while they are in their natural corruption (by decree and eternal consent), which does not involve a spiritual union.

Section 3 describes a certain spiritual union in effectual calling before faith, which produces faith, since faith flows from spiritual life.  Section 4 is of the mutual spiritual union upon faith, with Christ’s benefits following.

Witsius’s teaching is in accord with the Westminster Larger Catechism below.

Halyburton, Thomas – Section XI  in ‘A Modest Inquiry whether Regeneration or Justification has the Precedency in Order of Nature’  in The Works of the Rev. Thomas Halyburton…  (London : Thomas Tegg, 1835), p. 553



Samuel Rutherford

Survey of Spiritual Antichrist, Pt. 2, ch. 61, ‘How Faith Justifies…’, p. 108

“Objection 1 [of Saltmarsh, an Antinomian]:  ‘Christ is not ours by any act of our own, but by an infinite act of God’s imputing his righteousness.  Therefore, Christ is not ours by faith.’

[Rutherford’s] Answer:  Christ is not ours, by any act of our own, as by a ransom, a meritorious and principal cause. [This is] True, therefore [Saltmarsh concludes], [Christ is] not [ours] by faith, as a condition knowing, apprehending, feeling, applying, receiving, [and] opening the everlasting doors, that the King of glory may enter in.  It’s false [that is, Saltmarsh’s inference].

So bread is ours only by an omnipotent act of Him that causes the earth to bring forth, as by the first principal and effectual cause: Therefore [Saltmarsh would conclude], bread is not our’s in a civil way, by plowing, sowing, earing, and in a spiritual way, by laying hold by faith on the Covenant, in which the world, the things of this life, are made ours (1 Cor. 3:21); this is a lax and vain consequence.”


Westminster Larger Catechism


Note that Westminster defines union with Christ, not as an act, but as a work, and that not before effectual calling.  Nor does it define it as only occuring upon, or after, faith, but in connecting it with effectual calling leaves it open that the inception of the spiritual union, in a certain respect, may be before faith.  Witsius teaches such above.


“Q. 66. What is that union which the elect have with Christ?

A. The union which the elect have with Christ is the work of God’s grace,[f] whereby they are spiritually and mystically, yet really and inseparably, joined to Christ as their head and husband;[g] which is done in their effectual calling.[h]

[f] Eph. 1:22Eph. 2:6-8
[g] 1 Cor. 6:17John 10:28Eph. 5:23,30
[h] 1 Pet. 5:101 Cor. 1:9



That Spiritual Union to Christ is the Fount of Justification, Adoption, Sanctification & Glorification


Westminster Larger Catechism [See also the ordering of the questions that follow this question]

“Q. 69. What is the communion in grace which the members of the invisible church have with Christ?

A. The communion in grace which the members of the invisible church have with Christ, is their partaking of the virtue of his mediation, in their justification,[t] adoption,[v] sanctification, and whatever else, in this life, manifests their union with him.[w]

[v] Eph. 1:5

Richard Muller

‘unio mystica sive praesentia gratiae tantum’  in Dictionary of Latin & Greek Theological Terms: Drawn Principally from Protestant Scholastic Theology  1st ed.  (Baker, 1985), pp. 314-5

“The orthodox therefore define the unio mystica as the spiritual conjunction (conjunctio spiritualis) of the Triune God with the believer in and following justification.  It is a substantial and graciously effective indwelling.

In relation to the ordo salutis (q.v.), or order of salvation, the Protestant scholastics distinguish the initial unitio (q.v.), or uniting, of the unio mystica, which is the basis for the imputation of Christ’s righteousness to the believer and which corresponds with the adoption (adoptio) of the believer, and the ongoing unio, or union, of the unio mystica, which continues concurrent with sanctification throughout the life of the believer…”
