John Chrysostom
The hostility resulting from sin The opposition that God held towards both Jews and Gentiles represented, in a sense, a middle state. This division, as long as the Law was in effect, was not only preserved but also reinforced.

Some believe this division referred to the Law, which prevented Jew and Gentile from mingling. However, I contend that Paul was not referring to the Law itself, but rather to the enmity of the flesh, which functioned as a dividing wall keeping us apart from God, as the prophet declares, ‘But your iniquities have made a separation between you and your God’ (Isaiah 58:2). This is indeed correct. Such a barrier, as the enmity of the flesh, obstructed access to God for both Gentiles and Jews. The Law did not eliminate this enmity; rather, it intensified it, for the Law, as the apostle states, produces wrath (Rom 4:15).
The significance of discipline is that it guides us towards God. A person with an injury has much to ponder—should they fear the decay or the surgeon's incision? Is it the blade or the widening wound that concerns them? Sin is akin to corruption, while discipline serves as the surgeon’s blade. A person with an infected injury endures discomfort, even without any surgical intervention; they are particularly in a dire state when no healing occurs. Similarly, the sinner lives in great distress, even if they face no immediate consequence; their suffering intensifies when they experience neither punishment nor adversity.

In terms of absolution of wrongdoing, if sin is what distances us from God, we must dismantle this detrimental barrier, and nothing will hinder our closeness to Him. Consider this incident: A nobleman from Corinth engaged in a sin that was shockingly uncommon among the Gentiles. He was a devout individual, one who had been near to Christ, and some even suggest he was part of the clergy. What was the outcome? Did Paul cast him out from the community of the redeemed? Certainly not; instead, he admonished the Corinthians repeatedly, both in this sense and in others, for failing to lead him toward repentance. To emphasize that no sin is beyond repair, he referred to this man, who sinned even worse than the Gentiles, saying, ‘Submit to Satan for the mortification of the flesh, that the spirit may be saved in the day of our Lord Jesus Christ’ (1 Cor 5:5).
