Which term refers to the communion of believers in heaven, purgatory, and on earth?

• A. One, Holy, Catholic, and Apostolic
• B. Grace
• C. The Church
• D. Communion of Saints

Answer: (D)

The term being tested refers to the spiritual unity of all believers across heaven, purgatory, and earth. This is the idea that those living on earth, souls in purgatory, and the saints in heaven are linked together in Christ through grace and intercession, forming one communion. This phrase is directly invoked in the Creed, expressing the belief that prayers and sufferings of the faithful flow throughout this connected body. The other terms point to different ideas: the first describes the four distinctive marks of the Church, not the cross-state fellowship of believers; grace denotes God's life given to us, not the structure of that fellowship; and the Church can mean the whole body of believers but does not specifically name the interconnected community of saints across all states.
