"This Jesus, who was taken up from you into heaven, will come in the same way as you saw him go into heaven." (Acts 1:11)

The Ascension
From the Council of Trent
Filled with the Spirit of God, and contemplating the blessed and glorious Ascension of our Lord, the Prophet David exhorts all to celebrate that splendid triumph with the greatest joy and gladness: Clap your hands, all ye nations: shout unto God with he voice of joy.... God is ascended with jubilee.
This, then, the faithful must believe without hesitation, that Jesus Christ, having fully accomplished the work of Redemption, ascended as man, body and soul, into heaven; for as God He never forsook heaven, filling as He does all places with His Divinity.
He ascended by His own power, not being taken up by the power of another, as was Elias, who was carried to heaven in a fiery chariot; or, as the Prophet Habacuc, or Philip, the deacon, who were borne through the air by the divine power, and traversed great distances.
Neither did He ascend into heaven solely by the exercise of His supreme power as God, but also by virtue of the power which He possessed as man. Although human power alone was insufficient to accomplish this, yet the virtue with which the blessed soul of Christ was endowed was capable of moving the body as it pleased, and His body, now glorified, readily obeyed the behest of the soul that moved it. Hence, we believe that Christ ascended into heaven as God and man by His own power.
