A great safeguard is the entire faith, the true faith, in which neither anything whatever can be added by anyone nor anything taken away; for, unless faith be one, it is not the faith.
Pope Leo II have neither permitted, nor shall I permit, the things which have been settled by the holy fathers to be violated by any innovation.
Pope Leo IBeyond our grasp, He chose to come within our grasp. Existing before time began, He began to exist at a moment in time.
Pope Leo IDavid's Lord was made David's Son, and from the fruit of the promised branch sprang One without fault, the two-fold nature coming together in one Person, that by one and the same conception and birth might spring our Lord Jesus Christ, in Whom was present both true Godhead for the performance of mighty works and true Manhood for the endurance of sufferings.
Pope Leo IAs the world attracts us with its appearance, and abundance and variety, it is not easy to turn away from it unless in the beauty of things visible the Creator rather than the creature is loved; for, when He says, 'you shall love the Lord your God from all your heart, and from all your mind, and from all your strength' (Mt. 22:37), He wishes us in nothing to loosen ourselves from the bonds of His love. And when He links the love of our neighbor also to this command, He enjoins on us the imitation of His own goodness, that we should love what He loves and do what He does.
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.
