In the New Testament seven orders are mentioned: Angels, Powers, Principalities, Dominions (ations), Thrones and Archangels. The Old Testament specifically mentions two others Seraph (im) and Cherub(im).
The New Testament and Old Testament refer also to the fallen angels. The Temptation of Adam and Eve presupposes the existence of bad spirits who were cast into hell from which they have no hope of redemption.
Angels are purely spiritual or bodiless persons (Mt 11:30), some of whom behold the face of God and thus are in bliss (Mt 18:10). These spiritual beings comprise the celestial court and are called angels (from the Greek for “messenger”) because, according to the Bible, they carry out missions at God’s command. In order to complete these missions, they can at times assume bodily form. According to the Bible, their missions are sometimes of great importance - eg, the Annunciation (Lk 1:26; 2:9-14).
The angels are the objects of God’s grace and love. But because, they are non-bodily creatures, their response to God’s love did not require time and reflection to grow and mature. As soon as they were created and received grace, they had the opportunity to respond to God’s love and be welcomed into bliss. While many did so, some did not.
The Church teaches that everyone has a guardian angel, based on references to them throughout the Bible.
CHOIRS OF ANGELS
Angels are ranked in the celestial hierarchy of Nine Orders:
Seraphim:
These are the highest order or choir of angels. They are the angels who are attendants or guardians before God’s throne. They praise God, calling, “Holy Holy Holy is the Lord of Hosts”. the only Bible reference is Isaiah 6:1-7. One of them touched Isaiah’s lips with a live coal from the altar, cleansing him from sin. Seraphim have six wings, two cover their faces, two cover their feet, and two are for flying.
Cherubim:
Cherubim rank after the seraphim and are the second highest in the nine hierarchies or choirs of angels. They are manlike in appearance and double-winged and were guardians of God’s glory. They symbolize God’s power and mobility. In the New Testament, they are alluded to as celestial attendants in the Apocalypse (Rv 4-6). Catholic tradition describes them as angels who have an intimate knowledge of God and continually praise Him.
Thrones:
Dominions:
Virtues:
Powers:
Principalities:
In the New Testament Principalities refers to one type of spiritual (metaphysical) being which are now quite hostile to God and human beings. (Rom 8:38; 1 Cor 15:24; Eph 1:21; 3:10; 6:12; Col 1:16; 2:10, 15) Along with the principalities are the powers (Rom 8:38; 1 Cor 15:24; Eph 1:21; 1 Pt 3:22; 2 Thes 1:7); and cosmological powers (1 Cor 15:24; Eph 1:21; 3:10; Col 2:15);Dominions (Eph 1:21; Col 1:16) and thrones (Col 1:16). The clarity of the New Testament witness helps see that these beings were created through Christ and for Him (Col 1:16). Given their hostility to God and humans due to sin, Christ’s ultimate rule over them (ibid) expresses the reign of the Lord over all in the cosmos. This is the Lordship of Christ, which reveals God’s tremendous salvation in conquering sin and death at the cross, and now takes place in the Church. (Eph 3:10)
Archangels:
Archangels are generally taken to mean “chief or leading angel” ( Jude 9; 1 Thes 4:16), they are the most frequently mentioned throughout the Bible. They may be of this or other hierarchies as St. Michael Archangel, who is a princely Seraph. The Archangels have a unique role as God’s messenger to the people at critical times in history and salvation (Tb 12:6, 15; Jn 5:4; Rv 12:7-9) as in The Annunciation and Apocalypse. A feast day celebrating the Archangels Michael, Gabriel and Raphael is celebrated throughout the Church September 29. A special part of the Byzantine Liturgy invokes the “Cherubic Hymn” which celebrates these archangels and the guardian angels particularly. Of special significance is St. Michael as he has been invoked as patron and protector by the Church from the time of the Apostles. The Eastern Rite and many others place him over all the angels, as Prince of the Seraphim. He is described as the “chief of princes” and as the leader of the forces of heaven in their triumph over Satan and his followers. The angel Gabriel first appeared in the Old Testament in the prophesies of Daniel, he announced the prophecy of 70 weeks (Dn 9:21-27). He appeared to Zechariah to announce the birth of St. John the Baptist (Lk 1:11). It was also Gabriel which proclaimed the Annunciation of Mary to be the mother of our Lord and Saviour. (Lk 1:26) The angel Raphael first appeared in the book of Tobit (Tobias)Tb 3:25, 5:5-28, 6-12). He announces “I am the Angel Raphael, one of the seven who stand before the throne of God.”
