Angels, God’s servants and messengers, sent by God to perform miracles and protect his children.
A guardian angel is an angel that is assigned to protect and guide a particular person, group, kingdom, or country. Belief in guardian angels can be traced throughout all antiquity. The concept of tutelary angels and their hierarchy was extensively developed in Christianity in the 5th century by Pseudo-Dionysius the Areopagite.
The theology of angels and tutelary spirits has undergone many refinements since the 5th century. Belief in both the East and the West is that guardian angels serve to protect whichever person God assigns them to, and present prayer to God on that person’s behalf.

The traditional Catholic prayer to one’s guardian angel:
Angel of God, my guardian dear
to whom God’s love commits me here.
Ever this day/night be at my side
to light, to guard, to rule and guide.
qui custos es mei,
me, tibi commissum pietate superna,
rege et guberna.
