"As we receive the bread and wine symbolizing Christ's broken body and spilled blood, we in imagination join in the scene of Communion in the upper chamber. We seem to be passing through the garden consecrated by the agony of Him who bore the sins of the world. We witness the struggle by which our reconciliation with God was obtained. Christ is set forth crucified among us. DA 661.1"
"And when he had given thanks, he brake it, and said, Take, eat: this is my body, which is broken for you: this do in remembrance of me."
The EGW passage directly refers to the bread and wine symbolizing Christ's broken body and spilled blood, which is a clear reference to 1 Corinthians 11:24 and the institution of the Lord's Supper.
"Looking upon the crucified Redeemer, we more fully comprehend the magnitude and meaning of the sacrifice made by the Majesty of heaven. The plan of salvation is glorified before us, and the thought of Calvary awakens living and sacred emotions in our hearts. Praise to God and the Lamb will be in our hearts and on our lips; for pride and self-worship cannot flourish in the soul that keeps fresh in memory the scenes of Calvary. DA 661.2 He who beholds the Saviour's matchless love will be elevated in thought, purified in heart, transformed in character. He will go forth to be a light to the world, to reflect in some degree this mysterious love. The more we contemplate the cross of Christ, the more fully shall we adopt the language of the apostle when he said, “God forbid that I should glory, save in the cross of our Lord Jesus Christ, by whom the world is crucified unto me, and I unto the world.” Galatians 6:14 . DA 661.3"
"But God forbid that I should glory, save in the cross of our Lord Jesus Christ, by whom the world is crucified unto me, and I unto the world."
EGW directly quotes Galatians 6:14.
"Saying with a loud voice, Worthy is the Lamb that was slain to receive power, and riches, and wisdom, and strength, and honour, and glory, and blessing."
Both passages speak of praise to God/the Lamb, and the sacrifice of Christ. The EGW passage speaks of praise to God and the Lamb, which is a theme in Revelation 5:12.
