A cloud of witnesses
But you have come to Mount Zion, and to the city of the living God, the heavenly Jerusalem, and to innumerable multitudes of angels, to the festal gathering and assembly of the firstborn who are enrolled in heaven, to God the Judge of all, to the spirits of just men made perfect, to Jesus, the mediator of a new covenant, and to the blood of sprinkling that speaks better than that of Abel.
Hebrews 12:22-24In context. The same letter: Christians have come to the heavenly Jerusalem, to angels, to ‘the spirits of just men made perfect’, and to Jesus the mediator of a new covenant.
Scripture is silent on it. Scripture says the departed in Christ are alive to God and part of one assembly with us. It is silent on whether they hear our requests.
The Catholic reading
Hebrews says we have come to the spirits of the just made perfect and are surrounded by a cloud of witnesses; Revelation shows the elders in heaven holding “golden bowls full of incense, which are the prayers of the saints”, an angel offering those prayers before God, and the martyrs under the altar aware of events on earth. The departed are not asleep or cut off.
“It is not merely by the title of example that we cherish the memory of those in heaven”
Catechism of the Catholic Church 957
The Protestant reading
The witnesses of Hebrews 12 are witnesses to faith, examples who have run; the picture is a race, not a conversation. Revelation’s elders carry prayers to God; no one in Scripture ever addresses a prayer to them. Awareness in heaven, if it is taught, is not the same as a channel from earth.
“in heaven they pray for the Church in general, albeit no testimony concerning the praying of the dead is extant in the Scriptures”
