Pope Leo I

The 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.

The Church is a virgin, the bride of one Spouse, Who is Christ, and this Church does not allow herself to be violated by any error; so that, throughout the whole world there may be for us one uncorruptedness of a single chaste communion.

No one, however weak, is denied a share in the victory of the cross. No one is beyond the help of the prayer of Christ.

The devil is always discovering something novel against the truth.

David'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.

Teach nothing new, but instill into all men's breasts those things which the Fathers of revered memory have with harmony of statement taught... Preach nothing else than what we received from our forefathers... Accordingly, both in the rule of faith and in the observance of discipline, let the standard of antiquity be maintained throughout.

And each one is a partaker of this spiritual origin in regeneration; and to every one when he is re-born, the water of baptism is like the Virgin's womb; for the same Holy Spirit fills the font, Who filled the Virgin, that the sin, which that sacred conception overthrew, may be taken away by this mystical washing.

I have neither permitted, nor shall I permit, the things which have been settled by the holy fathers to be violated by any innovation.

Beyond our grasp, He chose to come within our grasp. Existing before time began, He began to exist at a moment in time.

The Child, the Lord Jesus Christ . . . Word in our flesh, Wisdom in infancy, Power in weakness, and in true Man, the Lord of Majesty.

Virtue is nothing without the trial of temptation, for there is no conflict without an enemy, no victory without strife.

Truth, which is simple and one, admits of no variety.

A true worshipper is one whose mind has not been defiled with any false belief.

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.

God ordained for every man one and the same means of salvation.

The cross of Christ is the true ground and chief cause of Christian hope.

By Baptism we are made flesh of the Crucified
