Holy Angels celebrates its parish feast day on October 2: The Feast of the Guardian Angels.
The Lord, Himself, gives us some understanding about holy angels. He tells us of the love which causes the angels to rejoice over our salvation and to watch over us on all our paths (Matthew 18:10; Luke 15:10).
God’s love caused Him to give existence to reasoning beings, capable of knowing and loving Him, and participating in his blessedness. The first creation of this love was the bodiless, immaterial spirits who served Him and fellowshipped with Him.
The holy angels, those faithful to God, were strengthened with divine grace and became completely blessed. They are reflections of glory and the radiance of the Holy of Holies encompasses them. Delighting in the ecstasy of the contemplation of eternal beauty, they are possessed of immeasurable love and drink freely from the wellspring of blessedness. They are above all human limitations, limited only by the fact that they are created beings and servants.
The host of heavenly angels is beyond number. Despite their huge number, a perfect and harmonious order exists among the blessed heavenly powers. This order is the very beauty of perfection, wisdom, truth, and love. Traditionally, the bodiless beings are established into nine orders: Angels, Archangels, Powers, Dominions, Principalities, Virtues, Thrones, Cherubim, and Seraphim. These beings are subject to one another in perfect love and humility.
