Is there any mention in the writings of Ellen White that the Lord's Supper is a renewal of the covenant?

Yes, Ellen White typically links the Lord's Supper with the new covenant, although she generally does not use the literal phrase "renewal of the covenant." She teaches that Christ, in the service of the bread and the cup, assured the disciples of His redemption through the new covenant sealed by His blood; therefore, repeatedly partaking in the Supper brings believers back to embracing this covenant gift.

The Biblical Connection Between the Supper and the New Covenant

Jesus Himself instituted the Supper in the context of His impending sacrifice. The cup is not merely a memorial symbol of Christ's suffering: it directly points to the new covenant made effective through His blood.

“Likewise He also took the cup after supper, saying, ‘This cup is the new covenant in My blood, which is shed for you.’” Luke 22:20

The apostle Paul reiterates this truth for the church. When Christians partake of the bread and the cup, they proclaim the Lord's death—the very death by which the new covenant was ratified.

“This cup is the new covenant in My blood. This do, as often as you drink it, in remembrance of Me.” 1 Cor 11:25

What Ellen White Actually Writes

Describing the Last Supper, Ellen White explains that Christ gave the disciples not only visible symbols of His body and blood, but also a covenant assurance: He is their Redeemer, and all who receive Him by faith receive heavenly blessings.

She emphasizes that this covenant was to be ratified by Christ's own blood, and the Supper reminds us of His sacrifice for the forgiveness of sins.

Thus, her phrasing is very close to the idea of covenant renewal: the Supper points back to the covenant sealed by the blood of Christ and invites every participant to receive its promises afresh by faith.

What the Supper Does Not Mean

It is important not to understand "renewal of the covenant" as though Christ makes a new covenant each time or offers Himself as a sacrifice repeatedly. His death was perfect, sufficient, and accomplished once for all.

“By that will we have been sanctified through the offering of the body of Jesus Christ once for all.” Heb 10:10

Therefore, it is more accurate to say that the covenant does not need to be re-established, but the believer continually needs to return to Christ. During the Supper, one personally renews trust in the Savior, receives His forgiveness, acknowledges dependence on His grace, and reaffirms the willingness to live as a person of the new covenant.

Preparation of the Heart and the Ordinance of Humility

In the Adventist understanding, the Lord's Supper is coupled with the ordinance of foot washing. This is not simply a detached ritual preceding the bread and the cup. It helps believers come to the Lord's table in repentance, humility, reconciliation, and brotherly love. Jesus showed that cleansing and serving one another must be an ongoing part of His disciples' spiritual life.

“If you know these things, blessed are you if you do them.” John 13:17

Ellen White emphasizes that the ordinance of humility is a time for self-examination and the removal of estrangement among brothers and sisters. Consequently, participation in the Supper should never be a formality. It invites a person to look honestly at their relationship with God and their neighbors.

The Supper as a Proclamation of Hope

The Supper looks not only backward to Calvary, but also forward to Christ's return. In taking the bread and the cup, the church confesses that its salvation is grounded in Jesus' sacrifice, and its hope rests in His glorious coming.

“For as often as you eat this bread and drink this cup, you proclaim the Lord’s death till He comes.” 1 Cor 11:26

So the answer to the question can be formulated carefully and accurately: Ellen White states that Christ, in the Supper, pledged Himself to be our Redeemer through the new covenant. While she does not make the term "renewal of the covenant" her primary expression, her theological thought supports using it to describe a personal, faith-filled renewal of dedication to the already established new covenant.

In practical terms, as you prepare for the next Lord's Supper, it is worthwhile to ask God to search your heart, to be reconciled with anyone you have offended or avoided, and to consciously say to Christ: "I receive Your grace, Your forgiveness, and Your lordship in my life once again."
