Short answer
Yes, Catholics believe in angels as spiritual beings and messengers of God.
Full answer
Catholics believe in angels and demons, spiritual creatures created by God, the former as servants and messengers of the divine will, and the latter, by their free choice, distanced themselves from God and became His adversaries. According to the Catechism of the Catholic Church, angels play an essential role in the plan of salvation, serving as protectors and spiritual guides for humanity (Catechism 328-336). They help us walk in faith and resist the temptations of evil.
In contrast, demons are fallen angels who, driven by pride and rebellion, rejected God's love and now work to draw humans away from Him. These evil spirits, led by Satan, oppose the plan of salvation, but their power is limited by divine providence, and their ultimate defeat was secured by Christ's victory on the cross (Catechism 391-395).
In Sacred Scripture, we find numerous references to both angels and demons. Angels appear as messengers at crucial moments in the history of salvation, such as the announcement of Jesus' birth to the Virgin Mary (Luke 1:26-38) and in the protection of the faithful (Psalm 91:11). Additionally, the New Testament warns us about the actions of demons, who can tempt humans, as seen in Jesus' temptation in the desert (Matthew 4:1-11), but they are always subject to God's power (Luke 10:18).
The presence of angels and demons, as well as the powers mentioned in Ephesians 6:12, reminds us of the spiritual reality surrounding our earthly life. Our struggle is not only against the adversities of the material world but also against the forces of evil operating in the unseen. However, with the help of angels and God's grace, the faithful are strengthened to resist evil and persevere on the path of salvation.
