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.”

“Who knows his brother to sin a sin not unto death, etc. These and such things are asked according to the will of the Lord, which pertain to the duty of brotherly love. He speaks, however, of daily and light sins, which as they are difficult to avoid, so also are easily cured. But regarding the manner in which this mutual request should be carried out for sins, James more clearly indicates, saying: Confess your sins to one another, and pray for one another that you may be saved (James V). If, therefore, by speaking, or thinking, or forgetfulness, or ignorance you have perhaps erred, go to your brother, confess to him, ask for intervention. If he purely confesses to you, making you aware of his own frailty, and you piously intercede for his errors, correct him. But these things are said about lighter sins. Moreover, if you have committed something more serious, bring in the elders of the Church, and at their examination, punish yourself.”
