The article critically re-evaluates the authenticity of Luke 22:43-44, which describes Jesus’ prayerful agony in Gethsemane. Textual criticism, linguistic analysis, examination of manuscript evidence, suggest their genuineness. Structurally, the verses fit within a chiastic pattern that highlights Jesus’ divine strength received through an angel, emphasising Luke’s theological themes of divine support and Jesus’ obedience. Comparisons with Matthew, Mark, and John reveal Luke’s unique tradition (though in some points common with Johannine’s) of divine reassurance and angelic assistance, aligning with his Christology of Jesus as the divine Servant and New Adam engaging in spiritual combat against Satan. Internal linguistic evidence, such as Luke’s medical terminology and distinctive vocabulary, supports the verses’ Lukan origin. Theologically, vv. 43-44 reinforce Luke’s depiction of Jesus as the obedient Servant, experiencing divine strengthening amid suffering, aligned with Isa 53 and Daniel’s visions, portraying Jesus’ suffering as a cosmic struggle against darkness, justified as part of God’s salvific plan. The verses underscore Jesus’ role in divine project, his divine Sonship affirmed through angelic support, and the importance of prayer in confronting spiritual evil.
