St. Leo the Great. February 18
“Christian, recognize your dignity and, now that you share in God's own nature, do not return to your former base condition by sinning. Remember who is your head and of whose body you are a member. Never forget that you have been rescued from the power of darkness and brought into the light of the Kingdom of God."St. Leo the Great, Sermones
The sacraments are "the Hope of God's Glory".
St. Leo the Great, Sermones
The devil is always looking for someone to devour. In the same way, Mary is always looking for someone she can help in any way."
St. Leo the Great
"what was visible in our Savior has past over into His mysteries."
