The Seraphim are the highest ranking choir of angels in Heaven. These are the angels of love. They jubilantly and continually praise and adore God at His throne, ever singing "Holy, Holy, Holy is the Lord of hosts. Heaven and earth are full of Your Glory. Blessed is He Who comes in the Name of the Lord."

The Cherubim are the second highest ranking choir of angels in Heaven. These are the angels of the power and the wisdom of the Word. These angels also join in continuous singing of God's praises.

The Thrones are the third highest ranking choir of angels in Heaven. These are the angels of the life which proceeds from God and returns to Him. They join with the Seraphim and Cherubim in singing the eternal praises of God at His throne.

The Dominions are the first in the choirs of angels who are distributed throughout creation. This choir is God's mediators of the gifts of the Holy Spirit. At the end of time, they will secure the victory of God's Justice.

The Powers are second among the angels of creation. This choir carries God's laws and those of nature into all creation. They also help in maintaining God's Covenant with all mankind.

The Principalities are the stewards of all creation. They help govern all aspects of creation: countries, communities, weather, materials, and skills of individuals. They help guide all for the greater honor and glory of God and the salvation of mankind.

The Virtues are first in the choirs of angels which aid mankind in attaining eternal life. This choir is the keeper of Faith, Hope, Love, and of the Church. They help protect and sustain these virtues on earth.

The Archangels are the servants of the Blessed Virgin Mary. They aid her in praying for and protecting mankind from the evils of Satan. They continuously strive for mankind's eternal salvation.

The Angels are close participants with the Archangels and the Blessed Virgin Mary. They, too, help mankind in their daily lives, that we may attain eternal life.

The Guardian Angels are not a choir in themselves. Rather, they are members of an honorary office. These angels are from all of the various choirs, and are imitations of Christ in the sense that they descend to the earth to guide each member of mankind towards eternal life. Though these angels can guide us for our good, they are not permitted to interfere with an individual's freedom to choose between right and wrong. We still make our own choices, and must be rewarded or punished accordingly.
