Only in his physical separation from the historical scene can Jesus’ spiritual union with the entire world for all time be complete. Jesus left the world one day in order to be available to all people throughout all time. He had to dissolve bonds he had made with his friends, in order to be available for everybody. We move towards heaven to the extent that we approach Jesus.
The words of one of Blessed John Henry Newman’s parochial sermons inspire us on this great feast (PPS, vol. 6, no. 10): “Christ’s going to the Father is at once a source of sorrow, because it involves His absence; and of joy, because it involves His presence. And out of the doctrine of His resurrection and ascension, spring those Christian paradoxes, often spoken of in Scripture, that we are sorrowing, yet always rejoicing; as having nothing, yet possessing all things (II Cor 6:10).
“This, indeed, is our state at present; we have lost Christ and we have found Him; we see Him not, yet we discern Him. We embrace His feet, yet He says, ‘Touch Me not.’ How is this? it is thus: we have lost the sensible and conscious perception of Him; we cannot look on Him, hear Him, converse with Him, follow Him from place to place; but we enjoy the spiritual, immaterial, inward, mental, real sight and possession of Him; a possession more real and more present than that which the Apostles had in the days of His flesh, because it is spiritual, because it is invisible.”
