Pope Leo IThe faith of those who live their faith is a serene faith. What you long for will be given you; what you love will be yours for ever. Since it is by giving alms that everything is pure for you, you will also receive that blessing which is promised next by the Lord: the Godhead that no man has been able to see. In the inexpressible joy of this eternal vision, human nature will possess what eye has not seen or ear heard, what man's heart has never conceived.
