Central to the Catholic understanding of angels is the fundamental belief that God’s love overflows into his creation, the redemption, and the consummation of the world. The angels are a significant manifestation of God’s overflowing, transforming, and perfecting love for his entire creation. Enterprising minds wishing to know more about these spiritual creatures, therefore, will discover that angels are part of the vast unseen portion of God’s creation, that they diligently assist with the redemption of mankind, and that they will be participants in the new creation when Christ returns in glory (cf. Revelation 21:1). The Catholic approach to angels begins with the belief that we live in a created universe of things visible and invisible. Things visible include the material aspect of creation, namely those things that we can perceive with our senses. Things invisible include the spiritual aspect of creation which elude sight, hearing, smell, taste and touch.
