"The essence of perfection is to embrace the will of God in all things, prosperous or adverse. In prosperity, even sinners find it easy to unite themselves to the divine will; but it takes saints to unite themselves to God's will when things go wrong and are painful to self-love. Our conduct in such instances is the measure of our love of God."

St Alphonsus de Liguori

"God commands not impossibilities, but by commanding he suggests to you to do what you can, to ask for what is beyond your strength; and he helps you, that you may be able."

"When the devil has failed in making a man fall, he puts forward all his energies to create distrust between the penitent and the confessor, and so by little and little he gains his end at last."

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.
