A voice from the golden altar commands the captive angels of the Euphrates to be released. As noted above, the altar is Christ, who makes trials and tribulations a means of sanctification for souls and an increase of fervor and holiness in the Church. They also serve to spread the blessings of the Gospel for as Tertullian says: "The blood of martyrs is the seed of Christians. [1]
Christ Himself gives command to release the captive angels, thus showing that the enemies of the Church have no power against her unless God permits. The Church can say to her enemies as Christ said to Pilate: "Thou shouldst not have any power against me, unless it were given thee from above." [2]
14. The captive angels are demons who will arouse new enemies and increased enmities against the Church. In a figurative sense they represent the new enemies thus aroused against the Church, whether they be nations, individuals or secret societies hostile to her. Four, the number of universality, indicates how widespread will be their influence.
With the prophets of old the region of the Euphrates was ever the country whence came the enemies of God's people. Its mention here indicates that these new enemies will arise among nations already hostile to the Church. In a secondary sense the term may be taken literally to represent peoples from that region who are hostile to the Church.
