“Jesus was weak, hungry, and thirsty (cf. Mt 4:2; Jn 19:28). God can neither tire nor lack anything—so Jesus was not God.”
This claim misunderstands the central mystery of the Incarnation. God truly became man in Christ (Jn 1:14). As God, He remains eternally unchanging, almighty, and unshakable. As man, He truly took on everything that belongs to our human nature—except sin (Heb 4:15). Hunger, thirst, fatigue, or suffering are therefore not arguments against His divinity, but rather proof of the true Incarnation.
The New Testament makes both aspects clear: He is the Almighty who calms the storm (Mk 4:39), raises the dead (Jn 11:43–44), and is worshipped as the “Lord of glory” (1 Cor 2:8)—and at the same time, He is the one who sits tired at the well (Jn 4:6) and cries “I thirst” on the cross (Jn 19:28). This tension is not a contradiction, but the truth of the two natures: In the divine nature, He remains unshakably God; in the human nature, He shares our neediness.
The Church has formulated this precisely: “One and the same Christ, Son, Lord, only-begotten, recognized in two natures, without confusion, without separation” (Council of Chalcedon, 451, DH 301). It is not the divinity that hungers or suffers, but the assumed humanity—and yet it is the same God who suffers in the flesh.
That is why Ignatius of Antioch († c. 107) could paradoxically say: “My God was born… my God suffered and died” (Letter to the Ephesians 7.2; 18.2). Not because the divinity itself is changeable, but because the eternal Son has so intimately united the human nature to Himself that everything He suffers as man can be attributed to the Son of God Himself.
Counterargument from the other side
“Hunger and thirst are proof of human limitation—God cannot experience that.”
Brief refutation
Yes, God in Himself knows no lack. But the eternal Son truly assumed human nature in the Incarnation. Therefore, it is not a contradiction, but an expression of His love: God Himself experienced hunger and thirst to become like us in all things and to redeem us.
