Communion of saints and intercession
The saints participate in the life of the Church and may be invoked in prayer.
What it is: The Orthodox Church teaches that the Church includes the living and the departed in Christ, and that the saints may be honored and invoked as intercessors.
How the religion understands it: The communion of saints is seen as a concrete reality of ecclesial life, reflected in feasts, icons, hymns, and prayers. The intercession of saints does not replace the mediation of Christ, but is understood as participation in it.
Context: This belief is common to the ancient Christian traditions and is deeply rooted in the liturgy and memory of the Church.
