The whole air around us is filled with angels.

 
St. John Chrysostom, 4th century

The holy spirits in heaven have always indeed been spirits.
They can only be called angels when they deliver some message.
Those who deliver messages of supreme importance
are called archangels.
Michael means 'Who is like God?'
Gabriel is 'The Strength of God'
and Raphael is 'God's Remedy'.

 
St. Gregory the Great, 4th century

The angels are here;
they are at your side, they are with you,
present on your behalf.

 
St. Bernard of Clarivaux, 12th century

We are like children
who stand in need of masters to enlighten us;
God has provided for this by appointing his angels
to be our teachers and guardians.

 
St. Thomas Aquinas, 13th century

Though we have a very long and dangerous way to go,
with such protectors what have we to fear?
They who keep us in all our ways cannot be overpowered
or led astray, much less lead us astray.

 
St. Bernard of Clairvaux, 12th century

We have only to follow them,
stay close to them,
and we shall dwell under the protection of God’s heaven.

 
St. Bernard of Clairvaux, 12th century

May the angels who serve God continually in heaven
keep us safe from all harm on earth.

 
Roman Liturgy

The angels of God show us God's goodness
which surpasses in goodness the whole of creation.
