Catechism of the Catholic Church 350:
Angels are spiritual creatures who glorify God without ceasing and who serve his saving plans for other creatures: “The angels work together for the benefit of us all” (St. Thomas Aquinas, STh I, 114, 3, ad 3).
Prayer for Day 4
“God sends us the angel to free us, to lead us away from fear, to lead us away from misfortune.”
Father, in return, you ask that I listen to and respect my guardian, my angel.
Help me to learn to be docile. In being docile to the advice of this companion on my journey, I learn to be docile to your Holy Spirit.
“See that you do not despise one of these little ones; for I tell you that in heaven their angels always behold the face of my Father who is in heaven.”
Angel of God, my guardian, if I can learn to be docile to you, I will be like a child, humble, small, not arrogant. The docility that makes me great and leads to heaven.
Truly I tell you, unless you change and become like children, you will never enter the kingdom of heaven. Whoever becomes humble like this child is the greatest in the kingdom of heaven.
God, grant me the grace of docility, of hearkening to the voice of my guardian angel, the companion of my life, your ambassador who is beside me in your name.
Father, how good you are to us! Even after we lost your friendship by choosing sin, you did not leave us on our own. You did not abandon us, but came to walk with us, and you give us an angel to be a companion on the journey to heaven.
I give you thanks and I praise you for this grace, and ask for your help that I might always be attentive to and thankful for this friend you have given me.
(Cf. Pope Francis, morning homily, October 2, 2015).
