The Lord reassured them with a greeting of peace, verified His resurrection through the evidence of the wounds on His hands, feet, and side, and by partaking in a meal with them. He then articulated the necessity of His sufferings and glorification through the resurrection as foretold in the Scriptures, similar to how He had enlightened the Emmaus travelers regarding their understanding of the Scriptures.
Having reassured His apostles—excluding Thomas—of the truth of His resurrection, He departed from them, reiterating His message, "Peace be with you," thereby reminding them of their commission. Having fulfilled His earthly ministry, He entrusted His work to them. For this mission, He imparted a share of the divine powers requisite for their future calling, powers that He had rightfully acquired for humanity through His culminating act, which they could receive solely from Him, the Redeemer, and granted them the authority to wield these powers with the divine autonomy that He Himself would exert. This moment marked the culmination of the significant day of Christ's resurrection. The apostles came to understand that their Lord was sovereign over both life and death, and that His declarations concerning Himself were irrefutable; a miracle unprecedented in history, where an individual had risen from the dead. Consequently, their past experiences with Jesus regained their importance—they were once again His apostles.
However, when the Risen One appeared and chose not to remain with them as He had previously done, they realized that they were to develop a distinct relationship with Him moving forward. His appearance, now more spiritual than corporeal (as even His flesh had been imbued with spiritual essence), suggested a gradual transition for them from a once tangible, sensory connection to a purely spiritual and unseen relationship, which would be fully realized at the time of His ascension. It is likely that on the same day, He also appeared to James (1 Cor. 15:7).
