Westminster Confession of Faith

All saints, that are united to Jesus Christ their Head by His Spirit and by faith, have fellowship with Him in His grace, sufferings, death, resurrection, and glory:⁵⁰⁴ and, being united to one another in love, they have communion in each other's gifts and graces,⁵⁰⁵ 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.⁵⁰⁶

Saints by profession are bound to maintain a holy fellowship and communion in the worship of God; and in performing such other spiritual services as tend to their mutual edification;⁵⁰⁷ as also in relieving each other in outward things, according to their several abilities, and necessities. Which communion, as God offereth opportunity, is to be extended unto all those who, in every place, call upon the name of the Lord Jesus.⁵⁰⁸

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.⁵⁰⁹ Nor doth their communion one with another, as saints, take away, or infringe the title or propriety which each man hath in his goods and possessions.⁵¹⁰
