Catechism of the Catholic Church: 665- 667
665 Christ’s Ascension marks the definitive entrance of Jesus’ humanity into God’s heavenly domain, whence he will come again (cf. Acts 1:11); this humanity in the meantime hides him from the eyes of men (cf. Col 3:3).
666 Jesus Christ, the head of the Church, precedes us into the Father’s glorious kingdom so that we, the members of his Body, may live in the hope of one day being with him for ever.
667 Jesus Christ, having entered the sanctuary of heaven once and for all, intercedes constantly for us as the mediator who assures us of the permanent outpouring of the Holy Spirit.
Yes, Christ in his human form became hidden to the eyes of men as He ascended. In that same way, we as Christians must die to ourselves and be ‘hidden with Christ in God’’. To die to ourselves, we must strive to ‘kill everything in us that is earthly: sexual vice, impurity, uncontrolled passion, evil desires and especially greed, which is the same thing as worshipping a false god’ (Col 3.5)
Jesus’ (true God and true man) ascension reassures us that our faith isn’t a blind one and that if we struggle everyday to seek and carry The Cross (from the ‘little ones’ to the ‘big one’, if it is His will) as our Lord did, we too will share in the glory of the resurrection. We must begin to understand what privilege Jesus’ ascension presents to us. Not only has he left the Holy Spirit to comfort us during the challenging times, he has gone on to serve as our Defender and Mediator before the Father. We can and we should tap into this undeserving grace by constantly seeking His intercession and invoking the Holy Spirit, every second, every moment, every day.
