ACC ~ 2 Corinthians 13 v4

BELIEVERS MADE STRONG BY BEING WEAK. AMBROSIASTER: Paul is referring here to the personal experience of the apostles, who were made weak by being treated badly, imprisoned and beaten. … Believers are made strong by being weak. Death inflicted by unbelievers is life as far as believers are concerned, for they will rise again to reign with Christ. COMMENTARY ON PAUL’S EPISTLES.

CRUCIFIED IN WEAKNESS. CHRYSOSTOM: This is a difficult passage which causes problems for many people. What is meant here by “weakness”? In Scripture weakness can refer to bodily illness, and it can also mean not being securely grounded in faith. But there is a third possibility, and that is what we find here. Weakness can mean persecutions, trials, plottings and the like. Christ was not weak in body or in spirit, but he was persecuted and put to death. It was not because of any inherent weakness that he went to the cross; on the contrary, he chose to die in that way in order to give us life in the power of God. HOMILIES ON THE EPISTLES OF PAUL TO THE CORINTHIANS 29.2-3.

WEAKNESS HE ASSUMED. SEVERIAN OF GABALA: Earlier Paul said that Christ became sin and a curse for us, even though he knew no sin and was not a curse in himself. Likewise here he says that Christ was crucified in weakness, even though this weakness was not his own but rather something which he assumed on our behalf. PAULINE COMMENTARY FROM THE GREEK CHURCH.
