The common element in all the special forms of contemplation is the loving, yearning, affirming bent toward that happiness which is the same as God Himself, and which is the aim and purpose of all that happens in the world.

Happiness and joy are not the same. For what does the fervent craving for joy mean? It does not mean that we wish at any cost to experience the psychic state of being joyful. We want to have reason for joy, for an unceasing joy that fills us utterly, sweeps all before it, exceeds all measure.

If God really became incarnate, and if His Incarnation can with justice compel man to change his life,then we have no alternative but to conceive of this Incarnation as something which is still present and which will remain present for all future time. ... What happens in the liturgical celebration of the Eucharist is something for which all religions of mankind have exressed longing, dimly sensed was coming, and as a rule even prefigured- the physical presence of the divine Logos made man, and the presence of his sacrificial death, in the midst of the congregation celebrating the mysteries.

The "supreme good" and its attainment -- that is happiness. And joy is: response to happiness.

No one can obtain felicity by pursuit. This explains why one of the elements of being happy is the feeling that a debt of gratitude is owed, a debt impossible to pay. Now, we do not owe gratitude to ourselves. To be conscious of gratitude is to acknowledge a gift.
