about the Ascension

quote below from comments from Acts 1 on the ascension from the Navarre Bible commentary:

Our Lord's ascension is one of the actions by which Jesus redeems us from sin
and gives us the new life of grace. It is a redemptive mystery "What we have al-
ready taught of the mystery of his death and resurrection the faithful should deem
not less true of his ascension. For although we owe our redemption and salvation
to the passion of Christ, whose merits opened heaven to the just, yet his ascen-
sion is not only proposed to us as a model, which teaches us to look on high
and ascend in spirit into heaven, but it also imparts to us a divine virtue which
enables us to accomplish what it teaches" ("St Pius V Catechism" I, 7, 9).

Our Lord's going up into heaven is not simply something which stirs us to lift up
our hearts--as we are invited to do at the preface of the Mass, to seek and love
the "things that are above" (cf. Col 3:1-2); along with the other mysteries of his
life, death and resurrection, Christ's ascension saves us. "Today we are not only
made possessors of paradise", St Leo says, "but we have ascended with Christ,
mystically but really, into the highest heaven, and through Christ we have ob-
tained a more ineffable grace than that which we lost through the devil's envy"
("First Homily on the Ascension").

The ascension is the climax of Christ's exaltation, which was achieved in the first
instance by his resurrection and which--along with his passion and death--const-
itutes the paschal mystery. The Second Vatican Council expresses this as fol-
lows: "Christ our Lord redeemed mankind and gave perfect glory to God [...]
principally by the paschal mystery of his blessed passion, resurrection from the
dead, and glorious ascension" ("Sacrosanctum Concilium", 5; cf. "Dei Verbum",
19).

Theology has suggested reasons why it was very appropriate for the glorified Lord
to go up into heaven to be "seated at the right hand of the Father." "First of all, he
ascended because the glorious kingdom of the highest heavens, not the obscure
abode of this earth, presented a suitable dwelling place for him whose body, rising
from the tomb, was clothed with the glory of immortality. He ascended, however,
not only to possess the throne of glory and the kingdom which he had merited by
his blood, but also to attend to whatever regards our salvation. Again, he ascen-
ded to prove thereby that his kingdom is not of this world" ("St Pius V Catechism",
I, 7, 5; cf. "Summa Theologiae", III, q. 57, a. 6).

The ascension marks the point when the celestial world celebrates the victory
and glorification of Christ: "It is fitting that the sacred humanity of Christ should
receive the homage, praise and adoration of all the hierarchies of the Angels and
of all the legions of the blessed in heaven" (St. J. Escriva, "Holy Rosary", second

glorious mystery).
