"The gift of Christ to the marriage feast was a symbol. The water represented baptism into His death; the wine, the shedding of His blood for the sins of the world. The water to fill the jars was brought by human hands, but the word of Christ alone could impart to it life-giving virtue. So with the rites which point to the Saviour's death. It is only by the power of Christ, working through faith, that they have efficacy to nourish the soul. DA 148.4 The word of Christ supplied ample provision for the feast. So abundant is the provision of His grace to blot out the iniquities of men, and to renew and sustain the soul. DA 149.1"
"For as often as ye eat this bread, and drink this cup, ye do shew the Lord’s death till he come."
Both passages connect a ritual (the Lord's Supper/marriage feast) with Christ's death and its significance for salvation. EGW amplifies the symbolism of the elements involved.
"At the first feast He attended with His disciples, Jesus gave them the cup that symbolized His work for their salvation. At the last supper He gave it again, in the institution of that sacred rite by which His death was to be shown forth “till He come.” 1 Corinthians 11:26 . And the sorrow of the disciples at parting from their Lord was comforted with the promise of reunion, as He said, “I will not drink henceforth of this fruit of the vine, until that day when I drink it new with you in My Father's kingdom.” Matthew 26:29 . DA 149.2"
"But I say unto you, I will not drink henceforth of this fruit of the vine, until that day when I drink it new with you in my Father’s kingdom."
EGW directly quotes Matthew 26:29 and references 1 Corinthians 11:26, making the connection explicit.
"For as often as ye eat this bread, and drink this cup, ye do shew the Lord’s death till he come."
Ellen White directly references 1 Corinthians 11:26 in this passage.
"The wine which Christ provided for the feast, and that which He gave to the disciples as a symbol of His own blood, was the pure juice of the grape. To this the prophet Isaiah refers when he speaks of the new wine “in the cluster,” and says, “Destroy it not; for a blessing is in it.” Isaiah 65:8 . DA 149.3"
"Thus saith the Lord, As the new wine is found in the cluster, and one saith, Destroy it not; for a blessing is in it: so will I do for my servants’ sakes, that I may not destroy them all."
EGW directly quotes Isaiah 65:8 to support her argument about the type of wine Jesus used.
It was Christ who in the Old Testament gave the warning to Israel, “Wine is a mocker, strong drink is raging: and whosoever is deceived thereby is not wise.” Proverbs 20:1 . And He Himself provided no such beverage. Satan tempts men to indulgence that will becloud reason and benumb the spiritual perceptions, but Christ teaches us to bring the lower nature into subjection. His whole life was an example of self-denial. In order to break the power of appetite, He suffered in our behalf the severest test that humanity could endure. It was Christ who directed that John the Baptist should drink neither wine nor strong drink. It was He who enjoined similar abstinence upon the wife of Manoah. And He pronounced a curse upon the man who should put the bottle to his neighbor's lips. Christ did not contradict His own teaching. The unfermented wine which He provided for the wedding guests was a wholesome and refreshing drink. Its effect was to bring the taste into harmony with a healthful appetite.…
"Wine is a mocker, strong drink is raging: and whosoever is deceived thereby is not wise."
EGW directly quotes Proverbs 20:1 and attributes the warning to Christ.
"As the guests at the feast remarked upon the quality of the wine, inquiries were made that drew from the servants an account of the miracle. The company were for a time too much amazed to think of Him who had performed the wonderful work. When at length they looked for Him, it was found that He had withdrawn so quietly as to be unnoticed even by His disciples. DA 149.5"
"When the ruler of the feast had tasted the water that was made wine, and knew not whence it was: (but the servants which drew the water knew;) the governor of the feast called the bridegroom, And saith unto him, Every man at the beginning doth set forth good wine; and when men have well drunk, then that which is worse: but thou hast kept the good wine until now."
The EGW passage describes the reaction to the miracle and the inquiries made about the wine's quality, which are directly related to the events described in John 2:9-10. It expands on the immediate aftermath and the servants' role, making it a thematic parallel.
