[from A Faith and Culture Devotional, Zondervan, 2008]
When he opened the fifth seal, I saw under the altar the souls of those who had been slain for the word of God and for the witness they had borne; they cried out with a loud voice, “O Sovereign Lord, holy and true, how long before thou wilt judge and avenge our blood on those who dwell upon the earth?”( Revelation 6:9-10)
During the first centuries of Christianity, the church was battered within and without. Pseudo-Christians distorted the faith and misled the faithful, while the powerful Roman Empire persecuted Christians with torture and death. When local church members were able to gather the remains of their fellow-believers (often, this was forbidden), they lovingly interred these broken bodies beneath their altars, a reminder that the blessed departed are invisibly present to join us in worship. St. John writes that, in his vision, he heard the voice of the martyrs crying out from under the altar.
