If we are one with Christ in the Mass in the living memorial of the Sacrifice of the Cross, we are one with Christ in His Eternal self-offering in the inner life of the Blessed Trinity. That is why the Holy Eucharist is a pledge of future glory as well as a sacrifice for sin. To belong to Christ and to receive Him in Holy Communion is a foretaste of the union and communion that we can enjoy for all Eternity if we remains faithful.
It was as a 'cloud' over the earth had been rent apart, when Jesus toured Galilee, speaking the truth about the purpose of life, the glory of the Father, the need for repentance, and for Baptism. He showed out God's nature and God's Will. He revealed the extent of Divine Love by accepting death on a Cross, rather than give up His Mission. He proved His Divinity by His miracles, above all by His Resurrection.
Many priests fail to mention the Cross. Jesus died on it, because of our sins. Few warnings are given from the pulpit, by many priests, about the serious sin by which people condemn themselves to Hell if they do not repent before they die. Many are lost because they have failed to repent of their adulteries, suicides, abortions, and lack of faith in God.
Jesus Christ is Divine. He is God-made-man, whereas His mother is only human - though very pure and holy. Christ did not simply use the Virgin Mary as a conduit for His arrival on earth. Her life is inextricably entwined with His, and will be so forever, as she intercedes for the Church, at His side in Heaven. It was by Divine grace that she was conceived Immaculate, worthy to be the mother of the Infant Jesus. She taught Him in His boyhood, then saw Him teach others, in His adult life. She suffered with Him, as He endured the Cross; and after His Resurrection and Ascension she guided the disciples. She was with them at Pentecost. But when her work on earth was done she was assumed, body and soul, to Heaven, to be with her beloved son forever, interceding for us who need their prayers.
Jesus crucified waits at the gate of Heaven, with His mother Mary and the holy angels. At our death, He looks for those who bear the marks of the cross and who are weary from His service; those who resemble Him, having persevered to the end out of love for Him.
