Bede, on 1John 5:16

“He that knoweth his brother to sin a sin which is not to death, let him ask, and life shall be given to him, who sinneth not to death. There is a sin unto death: for that I say not that any man ask.”

“There is a sin unto death, etc. A great question arises here, because blessed John clearly shows that there are certain brothers for whom we are not instructed to pray, whereas the Lord even commands us to pray for our persecutors. This can only be resolved by admitting that there are some sins among the brothers which are more grievous than the persecution by enemies. Therefore, the sin of a brother unto death occurs when, after the knowledge of God, which is given through the grace of our Lord Jesus Christ, someone attacks the brotherhood and is inflamed with envy against the very grace by which they were reconciled to God. However, a sin not unto death is if someone has not withdrawn love from their brother but has not shown the duties owed to brotherhood due to some weakness of mind. Therefore, the Lord on the cross says: Father, forgive them, for they do not know what they are doing (Luke 23). For they had not yet become participants in the grace of the Holy Spirit, nor had they entered the communion of holy brotherhood. And blessed Stephen prays for those by whom he was being stoned because they did not yet believe in Christ, nor did they fight against that common grace. And the apostle Paul, for this reason, I believe, does not pray for Alexander because he was already a brother; and he had sinned unto death, that is, by attacking brotherhood with envy. But he prays that those who had not severed love but had succumbed to fear be forgiven. For he thus says: Alexander the coppersmith did me much evil; the Lord will repay him according to his works; whom do you also avoid, for he has greatly resisted our words (2 Tim. 4). Then he adds for whom he prays, saying: At my first defense, no one stood with me, but all forsook me; may it not be charged against them (Ibid.). However, a sin unto death can be understood as one for which someone is forbidden to pray, because a sin that is not corrected in this life, its forgiveness is sought in vain after death. But if we carefully inspect the following, the previous sense of this reading seems to align more with its tenor. For it continues:”
