History and Miracle of the Trisagion Hymn
Above, the hosts of angels sing praise; below, men form choirs in the churches and imitate them by singing the same doxology. Above the Seraphim cry out the Trisagion Hymn; below, the human throng sends up the same cry. The inhabitants of heaven and earth are brought together in a common assembly; there is one thanksgiving, one shout of delight, one joyful chorus. ~ St. John Chrysostom
The unceasing and sanctifying doxology by the holy angels in the Trisagion signifies, in general, the equality in the way of life and conduct and the harmony in the divine praising which will take place in the age to come by both heavenly and earthly powers, when the human body now rendered immortal by the resurrection will no longer weigh down the soul by corruption and will not itself be weighed down but will take on, by the change into incorruption, potency and aptitude to receive God’s coming. In particular it signifies, for the faithful, the theological rivalry with the angels in faith; for the active ones, it symbolizes the splendor of life equal to the angels, so far as this is possible for men, and the persistence in the theological hymnology; for those who have knowledge, endless thoughts, hymns, and movements concerning the Godhead which are equal to the angels, so far as humanly possible. ~ St. Maximus the Confessor
