Salvation & the Sacraments
The Communion of Saints
The Church is one family in Christ — on earth, being purified, and in heaven — and death doesn't break the bond. So we can ask the saints in heaven to pray for us, just as we ask friends on earth, because they are alive in Christ and their prayers are powerful.
The saints in heaven present our prayers
In heaven the elders hold ‘golden bowls full of incense, which are the prayers of the saints,’ and the martyrs under the altar cry out to God. The saints are aware, active, and interceding.
A great cloud of witnesses — and they're alive
We are surrounded by a ‘cloud of witnesses,’ and come to ‘the spirits of the righteous made perfect.’ God is the God of the living; in Christ, the faithful departed are more alive than we are.
The prayer of the righteous is powerful
If ‘the effective prayer of a righteous person is very powerful’ on earth, how much more the prayer of the saints already made perfect in heaven? Scripture even shows departed holy ones interceding for God's people.
Common objections
“That's necromancy — forbidden in Deuteronomy 18.”
Necromancy is summoning spirits to gain hidden knowledge or power — a pagan manipulation. Asking a saint to pray for you is the opposite: humbly requesting intercession from a member of Christ's living Body. Note that Moses and Elijah, long dead, appear conversing with Jesus (Mt 17:3).
“Why not go straight to Jesus?”
We do — and we also ask others to pray for us, which Scripture commands. If asking a living friend to pray doesn't insult Jesus, neither does asking a saint who stands before his throne. It's the same Body, praying together.
