Jesus had previously assured them in His teachings in Galilee that they would be rewarded for their sacrifices by becoming judges of Israel, seated on twelve thrones. This promise, while spiritually profound, was taken literally by the disciples. Coupled with their hope that this journey could signify the last before the inauguration of the Messiah's reign during Passover, their imaginations were filled with delightful prospects, especially with the prevailing mood of the populace leaning favorably towards Christ.
Yet, as their hopeful thoughts dwindled and they confronted the stark reality of the past and present—realizing their vulnerability, poverty, and the malice of their adversaries—they found themselves engulfed by confusion and fear. In this state, which did not escape the notice of the Heartbreaker, the disciples wrestled with uncertainty; their fear stemmed from their indecision and lack of insight into the future. Thus, it became necessary for the Lord to clarify once more what they had not fully comprehended: in Jerusalem, He was destined not for a throne, but for a cross. This cross, while bearing profound sorrow, would ultimately fulfill the divine plan and bring salvation to mankind, highlighting a glory far surpassing any earthly honor they could imagine.
With that, the Lord called His disciples to Him, parting ways from the other travelers, and spoke to them clearly: “Behold, we are going up to Jerusalem, and the Son of Man will be delivered up to the chief priests and scribes; they will condemn Him to death and deliver Him to the Gentiles to be mocked, scourged, and crucified, and on the third day, He will rise again!” So precise and detailed were His words about His forthcoming fate, encapsulating both the sadness and comfort of the events to come. In their hearts, the disciples might have reasoned that since their Master would soon be betrayed, condemned, and crucified, He would also rise in glory; hence, worrying about His fate and their own seemed futile—the plans of the Most High must come to fruition.
However, rather than drawing such conclusions from His prophecy, the disciples failed to grasp His words at all. According to the Evangelist, they did not comprehend any of it: “And they understood nothing of these things; this saying was hidden from them” (Luke 18:34). Such incomprehension astounds us today, as we struggle to mentally place ourselves in the shoes of Jesus' disciples and fully embrace their thoughts and emotions. The disciples had never envisioned that the Messiah would perish, let alone in the shameful manner Jesus described—by crucifixion. Instead, they expected the immediate establishment of His glorious kingdom, and thus, could not interpret His words as intended.
To clarify, imagine a close friend of a prince who has heard that the king has named him heir to the throne, and having witnessed moments of favoritism from the king, is then told that the king will allow corrupt individuals to bring shame and suffering upon him, albeit having the power to prevent it. Would such a friend take his words at face value? Likely, he would search for some allegorical meaning, particularly if he knew his friend enjoyed speaking in parables. This is exactly what the apostles experienced; they probably interpreted their Master’s words through a lens of allegory.
Despite their misunderstanding, the Lord’s foretelling of His sufferings and death still holds value. For one, it was later revealed that the God-Man foresaw the horrors of the cross yet chose to embrace it voluntarily for humanity’s benefit. Furthermore, some disciples, when the time came for their Master’s suffering, would recall this foretold prophecy. Witnessing its tragic fulfillment could bolster their faith to anticipate the joy of His promised resurrection. Was it not this very prophecy that inspired St. John, who, despite his youth, would display greater courage during the events surrounding Jesus’ suffering and death than all of the other disciples?
