God promises to send an angel before the Israelites to protect and guide them. This celebration reminds us in a vivid and perhaps sentimental way of the reality and intimacy of God's presence. As God dwelt with and led the people in the Scriptures, so God remains with us now.
Jesus assures His disciples that they must become like little children if they wish to enter the kingdom of God. It is a call to an innocence and purity of faith that children possess but which adults sometimes find so hard to maintain. It is the faith of the childlike that God holds most dear.
To reflect on and profess belief in Guardian Angels may seem childish and embarrassing to adults. But this celebration reminds us of the promise of God's abiding presence, protecting and leading. It is a profession of our faith that we are never truly alone: God is ever with us.
Lord, may the Holy Angels protect us always from evil.
