Zanchi argues that we approach Christ’s divine person in a logical order. That is through the mediation of his humanity. In a treatise of his translated into English in 1594 entitled An excellent and learned treatise, of the spirituall mariage betvveene Christ and the church, and every faithfull man, Zanchi explains his justification for this idea. I offer below a brief selection of his argument to emphasize that for Zanchi the preaching of the Holy Scriptures and the administration of the sacraments play a key role in the church’s union with Christ, precisely because of this logical order of cognition. Zanchi is intentionally setting himself apart from the Zwinglians, who he says believe that the faithful are only united to Christ’s divinity, and the Lutherans who he says believe that Christ has an invisible body, which is not capable of nourishing us since it is completely unlike our bodies.
1. A faithfull man is first joyned to the flesh of Christ, and then afterwardes by the flesh, he is joyned to the word it selfe, or to the Godhead.
2. The reason is taken from knowledge. As it is with knowledge and the understanding of the minde, so is it also with voluntarie uniting and coupling. For the will followeth knowledge, and so far forth chooseth, willeth, and embraceth any thing, and uniteth it selfe thereto, as it doth thoroughlie understand and knowe the same. For it alwayes desireth not unknown but known good. But we do first and sooner apprehend & know Christ propounded in the word of God as he is man, then as he is God. Therefore in a certaine order of nature, and of the actions of teh minde and of faith, wee are first united to the flesh of Christ, and by that to his deitie, and so to his whole person.
3. I easily proove [this]…from the holy Scriptures. For, when God in the beginning of the world did promise a Redeemer, he promised and propounded him immediatly, as the seede of the woman, that is, as man, Gen. 3. “Her seede…shall bruise thy head.” So promised he also to Abraham: “In thy seede shall the nations be blessed.”
20. As therefore it was [in the Old Testament] the peoples dutie to come to the visible arke and there to wait and looke for the grace of God: so let no man hope for the grace of God, except he come to Christ visible man, and eate his visible flesh, and doe incorporate the same into himselfe by faith.
21. Wherefore it is clearer then the day light that a man cannot be united to the Godhead of Christ, except he be joyned to his humanitie, and to his flesh. For the flesh of Christ is the instrument of the Godhead, but it is this instrument onely, beeing taken and joyned inseparably into the unitie of the person.
22. This whole doctrine is very lively to be seene in the Sacraments, as it were in most cleere looking glasses.
23. There are two things in every sacrament: the visible signe, and the invisible grace: the earthly thing, and the heavenly. He that bringeth faith receiveth both.
24. But in what order? Even in the same, as they are propounded of God: by the signe we receive the thing signified: and by the earthly thing, we receive the heavenly thing: for God by the one doth offer the other.
And therefore that Chrsit doth still retaine his natural flesh, and doth imprint the virtue & efficacie, & as it were the image thereof, into our flesh, by communicating his holinesse with us, whereby we are made flesh of his flesh, and bones of his bones: also that he doth by the holy Ghost ingraffe our flesh into his flesh, & so quickneth our flesh by his flesh: and again, that the father doth communicate unto us nothing concerning salvation, but by the flesh of Christ truely and really communicated with us; and this they [i.e,. the church fathers] have prooved especially by the mysterie of the Supper of the Lord.
For as the bread is really and truly united unto us eating the same: so also is the flesh of Christ truly and in very deede united unto us who eate the same.
Because this union is made at the preaching of the Gospell in Baptisme, and in the Supper of the Lorde, therefore there are divers answeres made to this question [i.e,. the manner of how the union is made]. All confesse, that it is made at the preaching of the Gospell by faith alone: I say, an effectuall faith: neither is there any great controversie of the manner how it is made in baptisme: but there is no man ignorant how great contention there is even among those that professe Christ, of the manner how we are united to the flesh of Christ, and the flesh of Christ is united to us in the Supper of the Lord.
[We say] by faith also [Christ] is received of us into our harts, and we are united to him. Iohn 6. “Hee that eateth my flesh and drinketh my blood, abideth in me and I in him.” But hee is eaten and drunken by faith, as Christ in the same place expoundeth it, saying: “He that beleeveth in me shall never thirst.” Wee are therefore united to Christ by faith.
Wherefore, whether he be propounded to us in the Word, or in Baptisme, or in the Supper, Christ is alwaies united to us, and we unto him by his Spirit and by our faith… By the vertue & power of the same holy Spirit, we drinke in the supper, the blood of Christ, and growe together into one with him, and are quickened by his Spirit
