Westminster Confession of Faith Chapter 26
Of the Communion of Saints
All saints that are united to Jesus Christ their head by his Spirit, and by faith, have fellowship with him in his graces, sufferings, death, resurrection, and glory. And being united to one another in love, they have communion in each other’s gifts and graces; and are obliged to the performance of such duties, public and private, as do conduce to their mutual good, both in the inward and outward man.
Saints, by profession, are bound to maintain an holy fellowship and communion in the worship of God, and in performing such other spiritual services as tend to their mutual edification; as also in relieving each other in outward things, according to their several abilities and necessities. Which communion, as God offers opportunity, is to be extended to all those who in every place call upon the name of the Lord Jesus.
This communion which the saints have with Christ doth not make them in any wise partakers of the substance of his Godhead, or to be equal with Christ in any respect: either of which to affirm is impious and blasphemous. Nor does their communion one with another, as saints, take away or infringe the title or property which each man hath in his goods and possessions.
