. . . throughout this time which elapsed between the Lord’s Resurrection and Ascension, God’s Providence had this in view, to teach and impress upon both the eyes and hearts of His own people that the Lord Jesus Christ might be acknowledged to have as truly risen, as He was truly born, suffered, and died. And hence the most blessed Apostles and all the disciples, who had been both bewildered at His death on the cross and backward in believing His Resurrection, were so strengthened by the clearness of the truth that when the Lord entered the heights of heaven, not only were they affected with no sadness, but were even filled with great joy. And truly great and unspeakable was their cause for joy, when in the sight of the holy multitude, above the dignity of all heavenly creatures, the Nature of mankind went up, to pass above the angels’ ranks and to rise beyond the archangels’ heights, and to have Its uplifting limited by no elevation until, received to sit with the Eternal Father, It should be associated on the throne with His glory, to Whose Nature It was united in the Son. Since then Christ’s Ascension is our uplifting, and the hope of the Body is raised, whither the glory of the Head has gone before, let us exult, dearly-beloved, with worthy joy and delight in the loyal paying of thanks. For to-day not only are we confirmed as possessors of paradise, but have also in Christ penetrated the heights of heaven, and have gained still greater things through Christ’s unspeakable grace than we had lost through the devil’s malice. For us, whom our virulent enemy had driven out from the bliss of our first abode, the Son of God has made members of Himself and placed at the right hand of the Father, with Whom He lives and reigns in the unity of the Holy Spirit, for ever and ever. Amen.
Leo the Great, On the Lord’s Ascension (Sermon LXXIII)
A blessed solemnity of the Ascension to all who celebrate it today!
(I was going to say “to all western Christians” and then realised that eastern Catholics also celebrate the Ascension today, or at least I think that they do. And I also realised that not all western Catholics keep it today, as in certain parts of the western Catholic world it is transferred to Sunday, a rather unfortunate development. In any case, a blessed continued celebration of the Easter season!)
