"Yet eros and agape—ascending love and descending love—can never be completely separated. The more the two, in their different aspects, find a proper unity in the one reality of love, the more the true nature of love in general is realized. Even if eros is at first mainly covetous and ascending, a fascination for the great promise of happiness, in drawing near to the other, it is less and less concerned with itself, increasingly seeks the happiness of the other, is concerned more and more with the beloved, bestows itself and wants to “be there for” the other. The element of agape thus enters into this love, for otherwise eros is impoverished and even loses its own nature. On the other hand, man cannot live by oblative, descending love alone. He cannot always give, he must also receive. Anyone who wishes to give love must also receive love as a gift."

Pope Benedict XVI, Deus Caritas Est #7 (Vatican City 2005).

"In the account of Jacob’s ladder, the Fathers of the Church saw this inseparable connection between ascending and descending love, between eros which seeks God and agape which passes on the gift received, symbolized in various ways.

In that biblical passage we read how the Patriarch Jacob saw in a dream, above the stone which was his pillow, a ladder reaching up to heaven, on which the angels of God were ascending and descending (cf. Genesis 28:12; John 1:51). A particularly striking interpretation of this vision is presented by Pope St. Gregory the Great in his Pastoral Rule. He tells us that the good pastor must be rooted in contemplation. Only in this way will he be able to take upon himself the needs of others and make them his own: “per pietatis viscera in se infirmitatem caeterorum transferat". 4 Saint Gregory speaks in this context of Saint Paul, who was borne aloft to the most exalted mysteries of God, and hence, having descended once more, he was able to become all things to all men (cf. 2 Corinthians 12:2-4, 1 Corinthians 9:22). He also points to the example of Moses, who entered the tabernacle time and again, remaining in dialogue with God, so that when he emerged he could be at the service of his people. “Within [the tent] he is borne aloft through contemplation, while without he is completely engaged in helping those who suffer: intus in contemplationem rapitur, foris infirmantium negotiis urgetur.”5

"We have thus come to an initial, albeit still somewhat generic response to the two questions raised earlier. Fundamentally, “love” is a single reality, but with different dimensions; at different times, one or other dimension may emerge more clearly. Yet when the two dimensions are totally cut off from one another, the result is a caricature or at least an impoverished form of love. And we have also seen, synthetically, that biblical faith does not set up a parallel universe, or one opposed to that primordial human phenomenon which is love, but rather accepts the whole man; it intervenes in his search for love in order to purify it and to reveal new dimensions of it. This newness of biblical faith is shown chiefly in two elements which deserve to be highlighted: the image of God and the image of man."
