He has given his angels charge over you to guard you in all your ways. Let them thank the Lord for his mercy; his wonderful works are for the children of men. Let them give thanks and say among the nations, the Lord has done great things for them. O Lord, what is man that you have made yourself known to him, or why do you incline your heart to him? And you do incline your heart to him; you show him your care and your concern. Finally, you send your only Son and the grace of your Spirit, and promise him a vision of your countenance. And so, that nothing in heaven should be wanting in your concern for us, you send those blessed spirits to serve us, assigning them as our guardians and our teachers.
