5. The two natures of Christ, though really distinguished, yet were they inseparably joined, and made not two, but one person; so must our natures and persons though at greatest distance from God, be inseparably joined and united to Christ, and thereby also to God.¹ I Pray (saith Christ) that they all may be one as thou Father art in me, and I in thee, that they also may be one in us. That union of Christs two natures we call a personal hypostatical union, and this union of Christ with us, we call a mystical and Spiritual union; yet though it be mystical and Spiritual, this hinders not but that it is a true, real, essential, substantial union, whereby the person of the believer is indissolubly united to the glorious person of the Son of God. For our better understanding we may consider (if you please) of a threefold unity, either of persons of one nature, or of natures in one person, or of natures and Persons in one spirit; in the first is one God; in the second is one Christ; in the third is one Church with Christ; our union unto Christ is the last of these, whereby he and we are all spiritually united to the making up of one mystical body, O what a privilege is this! a poor believer, be he never so mean or miserable in the eye of the world, yet he is one with Christ, as Christ is one with the Father; our fellowship is with the Father, ²and with his Son Jesus Christ: every Saint is Christs fellow; there is a kind of analogical proportion between Christ and his Saints in every thing; if we take a view of all Christ, what he is in his Person, in his Glory, in his Spirit, in his Graces, in his Fathers Love, and in the access he hath to the Father, in all these we are in a sort fellows with Christ; only with this difference, that Christ hath the preeminence in all things; all comes from the Father first to Christ, and all we have is by Marriage with Jesus Christ; Christ by his union hath all good things without measure, but we by our union have them only in measure, as it pleaseth him to distribute. But herein if we resemble Christ, whether in his union with the Father, or in his union of the two natures in one Person of a Mediator; if by looking on Christ, we come to this likeness, to be one with Jesus Christ, Oh what a privilege is this!
