"For what would it profit us to know the whole Bible by heart and the principles of all the philosophers if we live without grace and the love of God?"

Thomas á Kempis

"A person who rails at God in adversity, suffers without merit; moreover by his lack of resignation he adds to his punishment in the next life and experiences greater disquietude of mind in this life."

St Alphonsus de Liguori

"The supreme perfection of man in this life is to be so united to God that all his soul with all its faculties and powers are so gathered into the Lord God that he becomes one spirit with him, and remembers nothing except God, is aware of and recognises nothing but God, but with all his desires unified by the joy of love, he rests contentedly in the enjoyment of his Maker alone."

St Albert the Great

The Incarnation

IN BRIEF

At the time appointed by God, the only Son of the Father, the eternal Word, that is, the Word and substantial Image of the Father, became incarnate; without losing his divine nature he has assumed human nature.

Jesus Christ is true God and true man, in the unity of his divine person; for this reason he is the one and only mediator between God and men.

Jesus Christ possesses two natures, one divine and the other human, not confused, but united in the one person of God's Son.

Christ, being true God and true man, has a human intellect and will, perfectly attuned and subject to his divine intellect and divine will, which he has in common with the Father and the Holy Spirit.

The Incarnation is therefore the mystery of the wonderful union of the divine and human natures in the one person of the Word.

- Paras 479 to 453 of The Catechism of the Catholic Church
