Gregory the Great, on 1Sam 14:45

“And the people said to Saul: Shall Jonathan then die, who hath wrought this great salvation in Israel? This must not be. As the Lord liveth, there shall not one hair of his head fall to the ground, for he hath wrought with God this day. So the people delivered Jonathan, that he should not die.”

“What then is the meaning of what is said, "Shall Jonathan then die," unless that another would have died for the same fault? By these words of the people there is surely shown to us the power of great discernment, because in the judgment of the elect, not only must the causes of faults be weighed, but also the merits of persons. This is openly shown by these words, because Jonathan is declared not to die not because he was the son of the king, but because he had wrought great salvation in Israel. When therefore great men fall, they are not to be handed over to the common judgment, because their prior works deserve that the gravity of their later faults be lightened. But this lightening of fault itself is not to be determined by respect of persons, but by regard for their prior life, because for his absolution the gains of Holy Church must be weighed, not carnal affection admitted. But what wonder if one's own merits avail for the absolution of a sinner, when from the authority of sacred Scripture we learn that some have been delivered for the sake of others? Indeed, by the good work of some, others are helped, as is said by the Lord to the sinning King Solomon: "Because you have not kept my commandments, I will surely tear your kingdom apart and give it to your servant. Nevertheless, in your days I will not do it, for the sake of David your father; but from the hand of your son I will tear it away" (1 Kings 11:11). Hence it is that not only do the works of fathers benefit their children, but we have also recognized that citizens are to be delivered for the sake of fellow citizens. Indeed the Lord promised to spare Sodom, which was to be overthrown, if He found in it only ten righteous persons (Gen. 18). Jerusalem also is said to be looked upon mercifully, because some good works were found in it. Hence it is that Eli, righteous in his own life but negligent in pastoral authority, heard from the man of God: "A great part of your house shall die when they reach manhood; nevertheless I will not utterly take away from you a man from my altar" (1 Sam. 2:33), so that sacred Scripture might here openly show that he was both struck for his laxity and regarded for his past manner of life. But he could perhaps be struck in part, because he had some impurity of life. Of Jonathan therefore it is well said: "Shall Jonathan then die, who has wrought this great salvation in Israel? Far be it! As the Lord lives, not a hair of his head shall fall to the ground, for he has worked with God this day." As if to say: He who has done great works has worthily deserved to be absolved entirely. Because therefore in ecclesiastical judgment, even if there is no respect of persons, there is nevertheless a discernment of merits, he fittingly concluded the sentence, saying: "So the people delivered Jonathan, that he should not die."”
