O God, who didst set thy blessed Bishop Saint Ambrose in thy Church as a Doctor and defender of the Catholic faith
and an example of apostolic fortitude: grant, we beseech thee; that aided by his intercession,
we may escape the dangers of error, and never be ashamed to confess thy truth; through Jesus Christ thy Son our Lord,
who liveth and reigneth with thee, in the unity of the Holy Ghost, ever one God, world without end. Amen.
